Hi, Sorry to hear you are experiencing so much vomiting. If you received your sleeve on 4/3, perhaps you are trying chicken out too early in your recovery phase(?) According to my surgeon's recovery schedule, I could not try chicken until at least one month after my sleeve surgical date. I started with applesauce, added yogurt and oatmeal, and slowly worked my way to trying seafood before trying out chicken. It so happens that I am 3 months out from my surgery and sometimes still experiencing problems with chicken (where I vomit after eating some). So I decided to wait several weeks before trying chicken again to see if that helps. I hope you feel better soon!
