What you have is fasting hyperglycemia - i have it too.

It is caused by insulin resistance. Your body is not using insulin right so your body just keeps pumping it even when you are asleep.

Bottom line on this is that it should be below 100. If its 100-110 you are considered insulin resistant. If it is 111-125 you are considered pre-diabetic, if it is over 125 you are diabetic.

Mine has never gone above 110 and I can control it somewhat by what I eat the night before, but mainly just by taking care of myself in general by exercsing and maintaining my low carb life style. I have not checked it for about two months. Eating low carb keeps it under 100 and I haven't worried about it since.
