For the last four evenings, I have had some real odd BG fluctuations:
--eat at 6:00PM and take appropriate amount of insulin for carbs; good BG
--Eat meal, BG goes down, and down. Treat low judiciously with juice.
--First time I am above my low threshold (80) all evening is about 12:15AM
--By 1:30AM, BG rising quickly, peaking at 233 at 5:15AM
Every recent night the same pattern emerges. Fine at dinner, bolus for carbs, BG plummets, then around 1-2 AM it rises very fast. I have tried a dual and square wave, with the same lows. And the lows are much below my 80 threshold--55, 61, etc.
For the high BG I did consider a liver dump, but I rarely experience that, usually only after a devastating low. I discounted that idea, as a result. I have counted carbs very carefully when eating dinner.
Here are my thoughts: lower the basal at 5:00 from .5 to .4 and change the dinner I:C ratio from 1 to 15 to 1 to 17. Raise the 10PM basal from .25 to .35 and the midnight basal from .4 to .5. That would provide an extra .9 units during the time my BG rises so quickly.
All input from you experts is always appreciated. Thanks.
