As for a prep before surgery, I didn't have one...which I though was strange but that's how my surgeon did it. Just nothing to eat or drink after 10pm the night before. When you wake up you will be pretty out of it. Expect some degree of pain but the nurses will be there for you to help manage that so try not to worry. You will do great don't worry. How many steps are you having the surgery done in?
DX UC - in 2005 when I was 37
Tried every drug-even Remicade-Tried diets-nothing worked
Step 1: J-pouch surgery (Laparoscopic restorative proctocolectomy w/ temporary diverting loop ileostomy) 6-25-10
Step 2: Take down surgery (Ileostomy reversal) 10/8/10
No more UC!!! Very happy with my results of this surgery!
