according to a nurse at my clinic this type of thing is common in both types of diabetes if caught really early, the pancreas behaves like a failing car part pretty much. it responds to the trigger of food in the digestive tract or whatever to release insulin to deal with it, but sits idle the rest of the time, the slight rises in BG overnight somehow not being enough of a stimulus. this is a very over-simplified picture but does kind of make sense if you think about it!
