Well, now, there's your problem.
It's my first ever bent cannula. It explained why I never saw numbers below 150 and why everything I ate made my numbers go crazy. The cannula is bent. OK, I'll change my set.
After I changed my set I awaited the magical drop in blood sugar and it... didn't happen. Instead my numbers stayed the same. I did a correction bolus and went higher. How is that possible? I'll tell you how that's possible...
Ah yes, bent cannula number 2. This one gave me even more alarming numbers than the last one. So, I yanked that set and started over.
Right now my BG is 138. Much better. New rule: When my numbers don't make sense, change my set. See, I can be taught!
