When i drink i have severe pains and nausea. its almost like having a gallbladder attack all over again for me..but i dont vomit…and i have been to the doctor and he put me on nexxium which didnt help so he sent me in for a egd…and i have two spots on the inside of my stomach so they gave me medication to clear those up….but i dont know if that is what was causing the pain from the alcohol….and i am afraid to try again lol! it is way to painful….and i also only got the attacks sometimes not everytime…..its almost just not worth drinking…or go ask the doctor b/c there is probably something that can be done so he can drink….
