Talk to Gastroenterologist on Stomach Problem

Whenever I eat anything, I get bound to spit. If I control and do not spit then I get jerks (aubaak) and many times, I vomit whatever I have eaten. (It happens AFTER eating mostly or drinking, if anyhow food digests then I'm OK.) I have consulted some doctors. Gone for (h pylori) and Hepatitis tests and they always come Negative. I have tried different combinations of medicines prescribed by the doctors, Omeperazole, Esomeprazole, Dexlansoprazole, Pantoprazole, Itopride and Levosulpiride. But I get fine untill I take any of above combination. Please I need permanent treatment. Thank you.
