I had my gastric bypass one week ago on 6/15...I agree that the pain was more than I anticipated and asked to stay 1 more night in the hospital as I was worried about being sent home with mostly Tylenol and wanted to make sure I could get pain controlled...I was trying to figure out what kind of pain was it - incision pain? gas pain? is this nausea? too much organ shuffling? When I was talking with nurses on my mini walks and started understanding the gas pumped in, she also said a lot of initial pain is from that...movement helped with getting myself to pass gas and that def helped...home now for 4 days and still have pain but manageable now...I too have had moments of "um why did I do this?" but I'm trying to focus on the longer term with a "this too shall pass" mantra in my heart. good luck to you and may you pass enough gas to feel comfortable again
