It's been 4 weeks since I had the sleeve (3/18/13)...it seems like I've developed acid reflux and not able get all my water in. I'm not able to eat tuna it egg whites because they make me throw up. I can keep down salmon, oatmeal, mashed potatoes and certain soups. Does anyone have any ideas on what to eat? Or what I should do about my water intake? I've only lost 28lbs since my surgery...should I be discourged?
