DD woke up at 170 today and corrected 1/2 unit along with breakfast. Within an hour she was feeling lightheaded. She tested at 80' but felt very odd, I had her Take a tab since she was at the peak of fast acting.....she promptly threw up. I had her retest (78) and take another tab since she threw up the first one. Each tab brings her up 24 or so, so even if she hadn't thrown up some of the first I'd expect her to be at 130 tops. 15 min later she was at 222. 10 min after at 275. Does this sound like a rebound??? I wonder if we caught the 80 on the way up?? We've never seen her react like this before.
