Recurrent nausea after stomach virus

[wantonwonderer]

I am a 24 year old woman. In early June I had a stomach virus consisting of intense nausea and diarrhea as well as aches and general malaise. Since then (now mid October) I have experience recurring nausea which is worse at night. It keeps me awake and I can hear and feel my stomach churning. I have seen two gastroenterologists. The first performed an upper endoscopy (normal accept for mild chronic inflammation in stomach and esophagus) and ordered as HIDA scan. The scan came back "borderline" (33% ef).  I have had a normal abdominal ultrasound and blood work. Negative for h.pylori, mono, and celiac sprue. Food allergy test inconclusive. Gastric emptying study normal. My doctor has ordered a subsequent HIDA scan (last one was 2 months ago), and I have yet to follow through on it.

I have been prescribed a host of PPIs, currently on Aciphex. I have also tried most anti-emetics: phenergan (only thing that helps but knocks me out), Zofran, and Tigan. Also, I have tried Hyomax which didn't seem to help much. I eat a very bland diet, essentially the same thing every day. I can feel fine for days at a time, and then be randomly sick for a day. The longest time I have felt okay was 2 weeks (recently), and last night I had a relapse. Up all night with nausea yet again.

I have been told that I am likely experiencing some kind of postinfectious IBS/dyspepsia which will gradually fade out over six months. I would very much like to believe this. Anyone else with postinfectious digestive problems experienced relief?  It certainly feels like something is very wrong with me. I am uncertain (as are my doctors) whether the gallbladder is the culprit as I have no pain and cannot correlate episodes to eating fatty foods. I do not feel consciously anxious during episodes, although I do become quite depressed as this sickness is ruining my life. Any advice or support would be SO appreciated, as I feel utterly alone in my suffering. Thanks
