I have always suspected that I had
hypoglycemia (by which I mean the chronic kind, whatever that may be called). I have all the classic symptoms, as my mother says. I need to eat every 2-4 hours, otherwise I become very lethargic, even rude. That's on the outside - inside I feel hungry, nauseous, have a headache, etc. I once passed out in high school because I hadn't eaten enough one day. I recently had a "physical" for a life insurance policy.
