I wake up nearly every day gassed up which feels like it is in my throat and makes me feel nauseated, however I never throw up. 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.
I had my gallbladder removed in 1974. Recently I had a complete Upper GI and they did say I had some slight esophogeal immotility and a small hiatyl hernia. I then had the scope put down into my stomach and the Doctor could find nothing wrong.
I am under a lot of stress at work, so don't know if this is causing it, but it makes me nervous and drives me nuts.
