I got up to go to the bathroom, and as always when I get up in the middle of the night, I checked my CGM, and it said 58 and dropping. OK. The bad part was the arrow pointed southeast. So not dropping fast. And then I looked at my pump, and somehow, in my sleep, I had programmed 298 carbs, and a square-wave bolus of 7.5 units at 1 AM. And I had told it my BG was 79.
Well, I better check it on my meter, and I'm looking at 48 with a significant amount of insulin on board, although I don't know how much. I suppose I could find that out on my Medtronic 722, but I THINK that involves programming another bolus, and I don't want to do that. And I'm NOT feeling the low, but if both the CGM and my meter are telling me I'm low, I think it's true.
So I'm sitting here at the computer eating carbs, which is a good thing to do, but the scary part is HOW in the world did I do that in my sleep? What if I hadn't woken up to pee?
So I'm kind of freaked out right now, and scared I'll do it again. And because it was a square-wave, I suspect I'm not done with it. :-(
