High FBG

Probably the Dawn Phenomenon, which you can read about if you do a search for it in the forum. Overall low carbing should gradually bring your FBG down over time. You could also try a small snack at bedtime and see if that helps.

Have a search round these forums, or Google, for Dawn Phenomenon and Liver Dump. There are a lot of threads where it is discussed. It is a natural occurrence whereby your liver is dumping glucose in your blood stream to keep you going.
