Square Root of Peanut Butter Toast

We noticed a pattern of postprandial spikes, and so the breakfast I:C went from 1:10 to 1:7. Okay. Breathe. Initially it seemed like a danger-huge wad of insulin, but we got used to it. Then the new, big dose stopped working.

It stopped working and every day saw a pp spike of 200+, sometimes even up to 300. Requiring a huge wad of correction. Come on. And the school schedule is such that the  spike occurs on the daily during math. People really need to be able to focus in math. This is a problem.


Peanut butter toast and milky tea math.

So today, after all those yucky spikes, we booped the breakfast I:C up to 1:5.
<—-this is the result of 1:5.  I guess I’ll dial it back to 1:6? Or scurry back to 1:7? Or?


PhotoMath math.

There’s way too much math in this house. On one hand, we have the simple (but complicated) math of insulin (make a simple carb ratio and massage it with one thousand squishy Adam Brown factors), and hope to not make someone completely ill.

On the other hand, 8th grade math. I have no idea what any of it means in terms of teddy bears on a see-saw or slices of pie, but it is simple, once you know the rules. Deeply simple. And if you follow the rules, you get the right answer. Which is lovely. But ultimately hollow.

Oh, if only the d-math could be harder, and then work out, like 8th grade math. This whole thing is like trying to make friends with an angry llama using nothing but an old tricycle horn and some candy corn.

Thank you, Leighann, for introducing me to the PhotoMath app. Silver linings.

    If this is dawn phenomenon, the fix could be in basal, not bolus. I dealt with the same thing for a really long time (years). Now I’m pretty much, but not entirely, resolved from it.

    In a rather simplistic way, here’s how. (Your numbers will likely vary, but the concept remains the same)
    Mid – 4am: basal 0.5 u/hr
    4am – 8am: basal 0.8 u/hr
    8am – 10:30 am: 0.3
    10:30am -5:30 pm: 0.525
    (After that, it doesn’t matter)

    The general idea is that the basal remains aboit 0.5 most of the time, but I give a little extra from 4-8am to cover the spike, then lower it to avoid a low. That extra (and early) 1.2 u (0.3 u times 4 hours) helps. In the end, its the same insulin just redistributed.

    Rather than add insulin to a breakfast mealtime bolus which can’t seem to work fast enough, I get it ahead of time as basal. And yeah, I run low if breakfast is late, but for the most part it works.

    Just a thought.

    The trick I’ve been finding with post meal spikes is to wait until I see my BG begin to dip on my CGM. It takes patience and time, (and finesse, which I don’t always manage) and which you may not have in the busy morning getting ready for school! But it generally makes all the difference.
