Why do I get the feelin almost like acid as if I were going to burp after I eat all the time and it takes forever to go away?

Maybe gastritis. A person who gets heartburn and burping after eating, may have an irritation of the stomach or esophagus. One may try to take antacids, acid blockers (ex:zantac), or acid reducers (ex:prilosec) for a time. If symptoms persist, see your doctor. An endoscopy may be performed. Chew your food, don't eat late, cut down caffeine; greasy, spicy and acidic foods, etoh, carbonated drinks, and tobbaco.
