There are studies that provide insightful data on the impacts of decision fatigue, and specifically diabetics.
When I wake in the morning, I need to know my blood sugar levels - it helps know where I am and informs me how well my basal insulin dose has been.
When I have breakfast I check again, it helps me calculate a corrective dose based on my personal carbohydrate ratios And current blood glucose levels. I then calculate the amounts of carbohydrates in this specific breakfast and the required amount of bonus insulin + corrective dose if required - making any adjustments for insulin I may already have in my system using a personal calculation of my insulin profile (how much of my insulin is active after 1 hour in my body, after 2 hours etc.) It also helps to retain the carbohydrate count of regular foods (croissant, 48g, but the high fat content changes it’s glycemic index - yup, gotta factor in the glycemic index!)
Check my blood levels again 2 hors later to make sure that was all okay. Repeat all steps for almost every snack (pre & post), for every meal (pre & post) then calculate any night time dose with enough confidence to avoid worrying about dying in my sleep while avoiding high blood sugar, which over time may turn me blind, make me lose a foot or stop my dick from working.
Catch a cold, and throw the whole effing thing out the window because that will change my insulin rations in an unpredictable way.
Then, adjust the ratios slightly based on season.
Then, adjust the ratios based on recent lockdown weight gain.
****, I mowed the lawn and forgot to have a snack - Hypo time, get ready to ride the blood-sugar-roller coaster.
Be polite. Remember not everyone is comfortable watching you take your shot. Where did you take your last shot? it’s important to rotate your injection sites. Do you have your glucose monitor, testing kits & lancets?
Then read some daft stuff on the internet while your blood sugar is too high and get way too involved in forum, which you‘d normally just let go...
If that was a long read, do it every couple of hours, every day for the rest of your life.
I make SO MANY small decisions every hour, of every the day... the ability to glance down at my watch is not tangentially related... It’s deeply connected to me feeling like a normal human being.
The Apple Watch isn’t the perfect health tool - but HealthKit, the Apple Watch, my CGMi, Carb counting Apps all work together to help improve my quality of life... not in a tangential way, in a tangible way.
*Rant over, waiting for my sugar levels to come down... too much carby pizza tonight !*
PS> Dear Tim... Keep pushing built in glucose monitoring please !
