There is a reason we don't go around routinely checking our glucose unless we have had initial screening and testing indicating a problem with it. The body is designed to maintain the right balance of insulin and glucose so that we don't have to go around connected to an IV for constant even administration - think about the nights while we sleep - the body manages to keep things in balance. It does this by raising and lowering levels as necessary, using glucose stores in the body, but it does not do it by the clock. So, no matter what "normal" or "average" may be, your body may be on a different schedule. I would not worry about this so much.
Everyone experiences times of occasional hypoglycemia and it's only when the body is incapable of maintaining the normal levels that we worry. This happens with diabetes.
If you are worried about your health, please schedule an exam with your doctor then explain the symptoms as you have described them here. There are plenty of reasons for fatigue, dizziness, feeling faint, etc. Blood sugar fluctuations are just one of these.
