I was sleeved on 6/23 and developed gastritis after week one. I am having a terrible time making the switch too. Everything makes me nautious and I gag, then vomit. So far I have managed to keep down Almond milk, Greek yogurt, SF pudding, mashed bananas, and SF Popsicles. Water alone is too harsh so I add a touch of flavoring. I haven't been able to keep down any protein I've tried (chicken and tuna). I also have trouble with protein shakes. Any suggestions folks have that may help would be appreciated!
