I had a nissen wrap operation in 1999. I still have problems at night after about 4 hours of sleep. I've tried all kinds of drugs to help relieve the gas. Right now I am on 40 mg of pantoprazole in the morning before breakfast. Most of the time days are fine. I have problems being regular on bowl movements, so I have a high amt of gas from the meds I take to go number 2. At night is when I have real problems. Any kindred spirits out there?
