I am confused. Just when I think I am getting a firm grip of controlling my BG's, I start waking up high. This has been happening for a couple of days now. My BG is 95 at bedtime and then in the morning, I wake up to 160. All day I have excellent control. 2 hrs after meals it has been 140 or lower. Could it be possible that I had a low overnight so my liver dumps out all this extra glucose? I don't think that this is the dawn phenomenon since this has only been occuring the last 3 or so nights.
