How quickly do your correction doses usually take to kick in? Is it rapid acting insulin? I find that I feel hypo when my bms drop rapidly, and you said your correction was 15 mins ago ... have you checked again to see what's happening there?
I have suffered with massive swings in blood sugars for many years (prior to starting on low carb diet, that is!) and have frequently felt hypo when high - and when I say high, I can be talking about bms in the 20s or even 30s in the extreme. Sometimes, it's not about where you are now, but where you've been and how quickly your bm is changing.
Basically, its a pain in the butt!! :roll:
