No Rhyme or Reason

Donuts are like the big No No for Sammie.  I guess the combination of fat and sugar just wreaks havoc on her blood sugar, raising it for hours regardless of the amount of insulin I give her.  At least that's been our experience in the nearly three years since Sam's diagnosis. So we avoid donuts now.  BUT it was Sam's B-day weekend and Grandma had come to visit AND there were suddenly donuts.  So, of course,  Sam had one...maple glazed with sprinkles...mmmmm.  I gave her the typical insulin for the carbs rounding up because it WAS a donut.  and a few hours later she was 262.  It was just after midnight. There shouldn't be anymore insulin on board now other than her Lantus.   I didn't correct...I don't know why...just wanted to wait.  She was 167 at 1:30am.  Ok. Good. She'll probably be a little high in the morning but we'll correct it then.  Well, like I said no rhyme or reason, she wakes up this morning at 73.   Boy am I glad I didn't give her even a half a unit at midnight like I normally would have.
