Just guessing, but are you taking insulin? That may count for the real low readings between 50-60. I can only imagine how sick you feel when it gets that low. I'd watch for things that might spike your blood glucose levels, like carbohydrates. I have to stay away from all starches... If I don't, my glucose levels are all over the board.
Speak with your physician or endocrinologist. An endocrinologist may be better able to help you understand the disease a little better and help you work on adjusting your meds.
