I had a horrible night last night. I hadn't eaten since lunch. I woke up at two am and got dizzy, faint and broke out in a cold sweat. I also got really nauseated. It lasted about a half hour until a while after I ate a granola bar and had some water. I know all of these can be symptoms of hypoglycemia but I'm not a diabetic. I feel fine now (finally) so I'm not too worried about it. I just don't know what the heck happened.
