I just found this forum, and hope someone can help. I've seen many doctors over 8 years who cannot figure out what my "episodes" are.... I've had about 8 - 10 of these total, sometimes weeks apart, sometimes years apart, but always exactly the same: Within the first hour after going to sleep, I awake with a profound wave of nausea and within 5 - 10 seconds I lose consciousness - whether I get up or stay in bed. (I used to get up to rush to the bathroom to vomit, but learned to just stay put - I don't hit the floor that way!!) After 30 - 60 seconds of unconcsiousness, I awake and vomit once, and have such weakness that I cannot move for about an hour. It takes about a day to fully recover. Doctors are puzzled because this occurs while lying in bed. I've seen cardiologists, neurologists, had sleep studies, ekgs, nothing ever shows up as abnormal. Does anyone recognize these symptoms? I'd be forever grateful for some help in figuring this out.
