I am taking esomeprazole but don't think it really works. I have tried ranitidine & omeprazole which didn't work either. I have been avoiding foods like tomatoes, onion, garlic, caffeine but I still find that I get this uncomfortable feeling instantly when I eat something that doesn't agree with me. The only way to relieve it is to bring it up but just lately my food is also coming back up. Sometimes i feel uncomfortable for hours and can't eat or drink anything. I had a total gastrectomy 14 months ago following stomach cancer & need to eat little & often & high calorie foods to keep my weight stable which is really difficult. I am also vegetarian so find it really difficult.
