I sometimes have an severe attack after I haven just eaten. I had one tonight in which my upper stomach felt like it was on fire. I belched several times and than vomited 3 times. Now I am fine. I also broke out in a cold sweat. I ate a steak with sautéed onions and mushrooms, baked potato with butter, sour cream and cheese and a salad with tomatos, lettuce, cheese, raw onion and ranch.
