Thanks for posting this! I've had this problem for a while and was convinced I was hypoglycemic but when I measured my blood sugar level, even at the peak of the symptoms, it was always perfectly normal. I had the blood glucose meter (and paranoia) because my sister is diabetic and I was afraid I might be too. It's somehow very comforting to be able to put a label on this and to know that it's not uncommon and (presumably) not dangerous.
