I've read about it a million times, but any tips & tricks other than what I already know never really sank in because a basal increase always solved the problem before. Starting yesterday after lunch, we've been stuck high - I'm talking high 200s to low 400s!!! At first, I thought I was just way off on the carbs (ate at Brigham's), but it can't still be that. Then I thought, maybe we're having an honest-to-goodness rebound. Whatever the reason, I can't get her down! Boluses are going through, corrections aren't making a dent. She's gone from 0.75u/hr to 0.90 in this time, and I threw in a couple of temp basals for good measure (so far, +25%; going for +30% in a minute). I actually skipped a couple of corrections and tried to get the temp basal to bring her down. We did a pod change last night, so that's not it. No ketones. This is insane.
