I would be interested in knowing the answer to this, as I thought it must be my bed, so went out and bought a new bed and mattress and it made no difference. (Except to the bank balance) I asked the nurse and she suggested I stopped taking the statins for a couple of weeks, that didn't make any difference either so it is back to the drawing board. My BG in the morning is now regularly over nine even though I have cut down on everything carbohydrate and sweet.
I expect the doctor will tell me it’s my age!!
