Let me explain why the pattern above troubles me. I have been having late afternoon lows off-and-on for months. Normally I would think I need less insulin except for a few pertinent facts:
- Last Bolus: 11:30 am
- Basal rate goes to zero (yes zero) at noon
- I use Apidra, so the last dregs of my insulin should be gone from my system by 3pm, at least that’s how it works the rest of the day
As you can see above, my numbers continue to drop well past 3pm. If I was to skip eating some glucose tabs, it would continue to drop until 5:30 or so. With hypo-unawarensss, that could make drive time dangerous if I forget to test around 4pm or so. I consume 4 glucose tabs which bumps my numbers up to the high-100s, but they start dropping again once the glucose peaks.
Both my educator and I are puzzled as to what could cause these late afternoon numbers to continue to drop, realistically there should be zero active insulin in my system by 3pm and most definitely by 4pm
Help a guy out, what the hell is going on?
