TU for replying. My doctor had suggested that I take simethicone and I did but it doesn't work too well for me. Before I had my reverse, I saw my gastro doctor who told me that I have an upper and lower digestive problem. I believe that the reverse nissen helped the upper but now I am still trying to find out what is causing the lower. The surgeon told me to try GasX. It helps some but the problem still exists. I also use DGL which helps to alleviate the gas in the colon. So I will keep searching.
