To take prilosec, pepto bismal, and aciphex (rabeprazole) for my acidic stomach. Howeverit doesnnausea. Are these normal side-effects of surgery?

Surgery? Are you talking about cholecystectomy (gallbladder surgery), I am assuming this is the case because usually it is followed by post-cholecystectomy syndrome, taking such medications for acidity indicates there is something serious needs to be taking care of with possibility of gastric ulcer.
