6-8 hours is right...I was on the table for 7 1/2 hours. I don't remember much of the first 2 days after surgery b/c I was pretty doped up on the pain meds...which is a good thing!
I didn't eat too much while in the hosptial (icky food anyway!) but by the time I got home I was eating small normal meals with my family. I remember stopping at Subway on the way home from the hosptial and devouring an italian sub!
All in all, it really wasn't that bad. Just keep your eye on the prize: No more UC and no more nasty drugs!!! Sending you well wishes for a speedy recovery!
