question: I have a history of barretts and need recheck in two yrs but ent doc sending me to gastro doc.. My question is getting up in middle of night about to vomit but cant. I eat late like 7pm and have incline pillow but still have to throw up. Not actually doing it though. I am terrified its cancer of stomach or esaphogus. Am I worried for nothing? 62 yrs female white
