I was wondering if anyone else had this sometimes. Sometimes i'll get it a couple times a week, sometimes not for weeks at a time. It comes on really suddenly and I feel weak, shaky, like I have hotflashes and eating seems to help. If I eat something, in a few minutes it will subside. I'm not diabetic and I've been tested for hypoglycemia and it's not that either. Just wondering if this is anothe part of CFS? Thanks!
