Looking for some help please... I had surgery for my j pouch take down 10 days ago. I came home after 5 days in the hospital and am still experiencing extreme nausea ( have thrown up a few times), watery output and am unable eat much of anything and am having trouble sleeping. I'm trying to sty hydrated. I have lost more weight since I've been home although that seems to have stabilized now. Any suggestions of what might be causing the nausea?
