Basically for the past year after I eat (not food biased) some food comes back up. Mouthfulls really that comes up with a burping. It is not vomiting. There is no wretching. I do not experience pain. My regurgitation is not acidic and can even begin as fast as coming up while I am sitting eating a meal or wait as long as 2 hours to come back up. I have had a bunch of tests all inconclusive, testing anywhere from motility issues to gallbladder issues and nothing. Any ideas??
