My resection was four months ago - I didn't even know I had Crohn's beforehand and I think it was better that way because I couldn't get nervous!
Worst part, hands-down, was the NG tube. I had it for the better part of a week and whenever it had to be unhooked (to walk, go to the bathroom, etc.) I would get sooo nauseated after as little as five minutes. After 3 or 4 days it shifted and was hitting my throat at just the right spot to make me gag like crazy, I had to beg the nurse to take it out but once they did, instant relief.
I was in the hospital for a week, went home for one day, and was back in the ER the next night - they had sent me home with a JP drain and the fluid coming out into it had changed colors, which ended up being because of a fistula at the anastomosis. You'll definitely be very sore, but if it's laparoscopic it probably won't be as bad (mine wasn't laparoscopic, I have a scar about as long as my hand). I was pretty much out of it for the first week, but I remember bathroom activities being extremely unpleasant - I had very little control and diarrhea was awful even for several weeks after I went home. They probably won't let you eat much, if at all, while you're in the hospital, and for a while after surgery you'll probably want to be really careful about what you try to eat. Potatoes and pasta were basically all I ate for a week or so after I got out of the hospital, everything else made me feel sick. Zofran was my best friend.
I went on Remicade the week after my surgery, I've had 4 doses so far and I really like it - the worst part is having to sit for 2 hours getting the IV. Good luck with your surgery, I hope it goes well for you!
