Hi Bomber :wave
Gallbladder surgery is usually pretty straight forward. You will probably be kept overnight just to make sure things are okay. It is done laparoscopically, so the recovery time is much shorter than the old way of doing it (large incision). You might have diarrhea after the surgery and for a while after due to the body having to adjust to the bile flowing in the intestines as opposed to staying in the gallbladder...basically, your intestines have to do the work of the gallbladder now.
I can't remember the brand name of the medication you are on, so I can't help now. If you go to [url="http://www.rxlist.com,"]http://www.rxlist.com,[/url] put in the name of the medicine (generic name is fine), and it will pull it up for you. It will list all of the adverse effects of the medication...it lists everything you would find in the PDR.
Good luck with your surgery!
