After eating breakfast and belching for a couple of hours it usually goes away. I also
gas up if I get very hungry which makes it hard to eat and get my
stomach full, which makes me gas up. I take two generic Prilosec every morning which helps, but I still wake up gassed up. After I get rid of the early morning gas, I belch quite a bit the rest of the day, but at least it doesn't nauseate me. I don't pass much gas, so it all appears to be in my esophagus and stomach.
