I am 14 days post op and I also felt crappy the first week mainly because of the air in my stomach. Since I have breathing issues, i stayed an extra day in the hospital. I never really had pain but was hugely uncomfortable. However, once i was moving around well the old bod got the engine running and the gas left. I do still burp but not as much. I have to say that I personally feel better than I have in two years and I am looking forward to it only getting better so hang in there!
