Replicating the Good Days

2 Comments

At the moment, I’m trying to replicate days like these.

Rather than these.

I have whole weeks where my carb counting is spot on, insulin just ‘works’ and blood sugars are simply effortless to manage. There are less highs, and less lows. The stream of good blood sugars seem to have somewhat of a flow on effect, so long as I can keep the train on course.

Then there are the weeks where blood sugars simply do not want to co-operate with the maths. Blood sugars feel like a lot of effort to manage, because naturally the insulin doesn’t work as well when levels are out of range. The urge to rage bolus is real, ultimately leading to more lows, and more rebound highs. It feels much more difficult to get the train back onto the course, rather than simply keeping it on the course.

In the midst of trying to pinpoint things, this was yesterday’s discovery.

11.1 was the greeting that I received from my FreeStyle Libre sensor after breakfast yesterday. It’s not what I was expecting, given that I had woken up to a blood sugar of 6.2 and carb counted my eggs on toast and milky coffee.

I gave an additional unit of insulin, and decided against reducing my basal rate for a day on my feet at work until that stubborn high started to come down.

Normally, a one unit correction while ripping open pallets of bulky furniture would send me plummeting. Yesterday, I was lucky to nudge the top edge of my target range.

As I recalled the day prior, my blood sugar had also remained stubbornly in the 8s despite repeated corrections. After increasing my basal rate in the evening and avoiding every urge in my body to rage bolus, I slowly but surely landed back into range by bedtime. Only to find that the ascent had begun once again when I checked at 1am.

By this point, I knew what had happened. In fact, I was feeling like an idiot that I had not picked up on this sooner.

Perhaps not as terrible as the banana bread highs that spoiled insulin had given me last time, but spoiled enough to make my blood sugars noticeably more stubborn to manage than usual.

Tools and technologies are only as smart as the people using them.

By sharing some more bits of the daily grind here, I’m hoping to make myself a bit more accountable to replicate more of those good days.

One Messy Night.

I was ready to go to bed.

As I watched my blood sugar slowly climb into the 10s, I gave a unit of insulin to correct. Thinking about the after effects of stacking my dinnertime insulin on top of a late afternoon coffee and one of Nonna’s biscotti, I set a temporary basal rate of 150% for 2 hours to help that insulin better do its job.

I set the alarm on my iPhone for 1am and switched off the lamp on my bedside. With a nagging feeling of doubt as I turned on my side, I fumbled for my pump in the dark and gave another unit.

DURN! DURN! DURN! DURN! 

I hastily fumbled for my phone to silence the shrieking alarm, before switching on my bedside lamp again. As I swiped my Libre reader, I was half expecting see blood sugars heading into low territory.

Instead, I was actually a pleasant 13.8.

I was in disbelief. However, I thought it could be plausible after having pasta for dinner. I reached for my insulin pump, and gave a rage bolus of 3 units.

ZZZZ! ZZZZ! ZZZZ! ZZZZ!

My rage clearly wasn’t enough to fuel the delivery of this bolus, which was stopped in its tracks by a very irritating occlusion alarm that was hissing and vibrating at me for attention.

I ripped the cap off my infusion site, which revealed a perfectly clear looking site. A poke and prod around the area showed no signs of any discomfort. I primed several units of insulin out of my pump line, watching it spill over the cannula and pool around the cap to satisfy my paranoia. I held my pump line up in the air and ran it through my fingers, watching it like a hawk for signs of air bubbles.

With my paranoia satisfied, I reattached the cap to my infusion site and delivered the remainder of the bolus that my pump had cut off. I set another temporary basal rate of 150% for the next two hours, setting my alarm for 3am.

When I stirred at 2.17am, feeling rather uncomfortable, my Libre reader revealed a reading of 17.7 and rising. I hastily grabbed my pump and went to deliver another rage bolus of 5 units.

ZZZZ! ZZZZ! ZZZZ! ZZZZ!

That hissing, vibrating occlusion alarm sounded once again, stopping my rage bolus in it’s tracks.

By this point, I was furious as I flung my bed covers away from me and was forced out of bed.

Finally, I ripped the infusion site away from my stomach. There was no kink in the cannula. There were no signs of blood, bruising or bleeding on my stomach where I’d placed the site. Everything looked fine, and I was convinced I had just wasted a perfectly good site.

After inserting a fresh infusion site, setting a temporary basal rate and delivering my third rage bolus of the night, I was finally able to close my eyes.

I wasn’t surprised to learn that I’d slept over my 6.25am alarm. I gulped down my coffee, showered, and hastily threw two pieces of frozen Pane Di Casa into my bag to toast at work.

I soldiered on, reminded of just how much responsibility rests on my shoulders every day.

Red Light.

I glance at the watch on my wrist. I know that it will only take me a minute, but it’s 4 o’clock and I really want to get out of here already.

I make the trek outside, where my car is conveniently parked in its usual spot at the end closest to the centre door. It’s a longer walk in the morning, when I have to come in through the back entrance, but completely worth it at the end of the day.

I hop inside my car, and place my belongings on the vacant seat beside me. I know that it will only take me a minute, but I really just want to start making my way home where afternoon coffee is calling my name.

I place my keys in the ignition, lock my doors and wind down my windows. I reverse out of my spot and make my way out of the carpark, cutting through some of the quieter residential areas in order to avoid the pile up of traffic on my way out of the centre. I make one final right, which takes me back out onto the main road and in a far better position traffic wise.

Finally, I have what I’ve been waiting for as I begin to apply my brakes, slide my gears back into neutral and cars begin to bank up in front of me. A red light.

I only have a minute, but I know I can do it.

I dive into my bag, pull out my travel case and grab my meter, strips and lancing device. I quickly pop open the cap on my test strip vial and slide out a fresh strip, sticking it into my blood glucose meter. I prick my finger with the lancing device, and squeeze my fingertip. A little drop of blood appears on my fingertip, but I know its not enough. I squeeze again, harder, like I’m holding on tightly for dear life.

Part of me knows I don’t have enough blood, but the other hasty part of my brain watching the traffic light tells me I can do this. I bring the meter closer to my fingertip, and let the blood slide onto the end of the test strip.

A shrill BEEEEEEP! Sounds from my meter as a strip fill error appears on the screen. My absolute pet hate when it comes to living with diabetes.

I furiously rip out the useless test strip, pop open the cap on my vial of strips and slide out a new one. I stick it onto the end of my meter, shove my lancing device right up against the tip of my finger and prick again. This time, blood flows more freely. Satisfied, the test strip laps it up and decides to give me a blood glucose reading.

I quickly wipe the excess blood on my fingertip against the side of the test strip as the light changes to green and traffic begins to move. I fling everything on the passenger seat beside me, which I’ll clean up during the next red light.

Review: AccuChek Guide Blood Glucose Meter

1 Comment

The AccuChek Guide has by far become my new favourite blood glucose meter in recent months.

I first received this meter from my friend Tammy of Diabetes: Forever and Always, before also picking up another one from the trade hall at the ADS-ADEA conference last year. There was, of course, no expectation that I would write or even use the meter itself.

The Guide has been around for a fair while, with it’s first claim to fame being the “spill proof” capped test strip vials.

Strips can also be easily accessed by simply sliding them out of their place, without having to stick your fingers in there and fumble around for one.

While this meter does use a slightly larger blood sample (0.6uL) compared to my FreeStyle Insulinx (0.3uL) and OneTouch Verio IQ (0.4uL), the accuracy more than makes up for it. Past meters have shown big variances from two consecutive readings, aren’t consistent with other meters, or the readings simply don’t match up with my feelings,. Even on grubby working hands, I have found the Guide’s accuracy to be the most consistent and superior.

I also like that I can see the blood go onto the strip, compared to my previous FreeStyle Lite strips which had me guessing whether it was blood or sweat had gone onto the strips.

My biggest gripe, as with other meters, is the strip fill errors. If I don’t get enough blood on the test strip on the first go, which often happens when I’m quickly trying to check during a red light on my way home, I have no choice but to start over with a fresh strip. Alternatively, both my Optium Xceed (does that meter still exist?) and the FreeStyle Insulinx gave me an additional 60 seconds to apply more blood.

One thing that disappoints me most is that every meter in the AccuChek family uses a different line of test strips. In comparison, the FreeStyle family only has two kinds of strips (to my knowledge). This definitely limits my enthusiasm to trial other meters, and does prove inconvenient when trying to stockpile test strips for spare or travel meters.

The guide comes with AccuChek’s FastClix lancing device, which is pretty damn amazing. Each cartridge change contains six lancets, meaning that I can change my lancet six times by simply sliding the little white knob. Unfortunately, this still does not motivate me to change my lancet any more often! There are also 11 depth settings, making the finger pricking experience pretty comfortable.

By far, my favourite feature of this meter is its Bluetooth connectivity to the AccuChek Connect smartphone app. Every time I check my blood sugar, the reading is wirelessly transferred to the app on my smartphone. The app makes it so convenient for me to review my blood glucose data, without the hassle of having to force myself to sit and upload each meter to my computer with its corresponding USB cable.

When you test your blood sugar as often as I do, you’ll get a nice graph of patterns and time in range, which has been really helpful to me while I’ve been adjusting to my pump break.

The app also has a built in bolus calculator that can be accessed with a single use code from a healthcare professional, however this feature has been recalled in Australia for some time. I’m currently using RapidCalc for bolus calculations on my iPhone while I’m on my pump break, but I would love to integrate my insulin dosing into the Connect app as well.

The biggest tradeoff to the additional features is a faster drain on the meter’s standard coin cell battery. I might get 2 months of battery life from checking my blood sugar 10 times per day on my main meter, alternating between a spare and a FreeStyle Libre as well.

The AccuChek Guide is an amazing, amazing meter that has all the bells and whistles for 21st century diabetes management. It definitely helps keep me feeling excited and motivated in managing my diabetes.

Bells and whistles aside, however, the biggest sell for me is that it’s a meter that I can trust.

It’s definitely worth asking your diabetes educator for one on your next visit.

Insulin Gone Bad.

I couldn’t help but notice the reading of 14.1. Is that high? My friend asked me from across the table as I was demonstrating my FreeStyle Libre.

Yeah, I obviously haven’t given enough insulin for the banana bread, I replied, pulling my pump out of my pocket and bolusing for another 30 grams of carbs ever so casually.

I had already bolused a very generous 60 grams of carbs for the slice of banana bread and iced coffee I had ordered at the local cafe, but I wasn’t overly surprised to see the upward trend arrow on my Libre.

My blood sugar was still skyrocketing by the time I arrived home an hour later, with my Libre clocking in at a lovely 17.4. I bolused for another 10g of carbs, bringing the total for my mid morning coffee catch up to an overly generous 100g of carbs. I was certain that all of this insulin was bound to kick in any minute now.

After another hour had passed and my Libre clocked in at 25, I had figured that banana bread was the devil. After a prick of the finger came in at 20.4, I ignored all insulin I had on board and gave a full 4 unit correction. I also set a temporary basal rate of 100% to help get things moving in the right direction.

After a bucketful of insulin, my blood sugars slowly but surely began moving in the right direction over the course of the afternoon.

When dinner time rolled around and I was back in range, I bolused for the 50 grams of carbs on my plate. I drank a glass of water. I stepped outside and turned the sprinklers on. I washed some strawberries that I planned on having post dinner. I drank yet another glass of water. I stepped outside again, and switched the reticulation off. After distracting myself for a good 20 minutes or so for the bolus to kick in, I finally tucked into my dinner with the hope of avoiding another blood sugar rollercoaster.

Fast forward to me in front of the television 2 hours later, and my blood sugar clocked in at 16.1 with an upward trend arrow on my Libre.

I scrolled back through my pump history, noting that my last prime was four and a half days ago. As I swapped out the infusion site, my brain began to cotton on to other moments of particularly difficult-to-manage post meal blood sugars in recent days.

The lone milky coffee that sent my blood sugar upwards of 10. The hot cross bun that I’d carefully pre bolused for, but landed me close to 20. Rising blood sugars, despite a long walk fuelled by 10g of chocolate beforehand. Even a pasta meal had been extremely difficult to manage.

As I connected all of these recent occurrences together, I eventually recalled another occurrence of skyrocketing levels when my insulin had spoiled 2 years ago.

My insulin had spoiled! There was my answer! 

So, maybe Banana bread wasn’t the devil after all.
