Bad day/ bad week… why?

A severe hypoglycemic reaction sent me to the emergency room last Sunday. I still don’t know what happened which is incredibly frustrating. I have had excellent control for years now and things had been going well.

At any rate ever since that episode I can’t seem to keep my BS down. Nothing seems to be working the way it was. I have increased my basal and upped my mealtime boluses but remain high all day long. (Extreme example: Went to bed with a 128. Checked at 3:00 AM and it was the same. Woke at 7:00 and it was 255. I don’t normally struggle with DP that much.)

Any guesses as to what has happened to me?
