Hi Amy,
Good luck with the surgery. Are you having a resection? My daughter has Crohn's, had one four and a half years ago and has been in remission ever since. She takes Immuran as a maintenance drug. She decided to have the surgery after having 3 flairs in 18 months. She decided to not eat rich foods, though I'm not sure if they would bother her if she did have them. She basically has a normal diet. She has a lot of energy. The surgery gave her her life back and I hope you also have good results.
Again, good luck. Please let us know how you are doing.
Debbie
