What's wrong with my stomach?

My mom is like that too. Some people just can't have too many drinks. Sounds like you had more than a one or two each time, which should be the limit. You can probably still drink, but I'd say to limit it to only one or two each month maybe - or even try to stop. If it gets worse I'd call the doctor, but I'd doubt it's something that can be treated. Unless you're allergic to it, there's nothing the doctor can do unless give you pain medicine. (That's what my doctor does if I have stomach problems with a certain food or drink.)
