I know lots of people who've had their gallbladders out and all of them seem to v* BEFORE they get it out (from whatever it was that made it necessary for removal--stones or whatever) and don't v* at all afterward. I agree with the others, just make sure they get something going in your iv for n/v and have injections/pills available for you after it's taken out. When I went under general anesthesia, after my iv was out, the nurses couldn't believe how I'd rather have the phenergan shots than feel a bit n*. LOL my thighs were their pincushions (and I didn't even feel n*! just took them as a precaution!).
So question--have you had any v* in conjunction with your attacks?
