I had the same symptoms as you last week. I was banded May 16, 2005...at 200lbs.....lost 85 lbs...and I started puking in my sleep, could not hold water or food down. Nothing in my band. Last thursday went to the er where my surgeon was at, they had to perform surgery. 5 Lapriscoptic incisions again..... I had a slip. Back on liquids. Was very dyhidrated
