dpol, I would definitely try cutting out sugar, carbs (especially gluten), and dairy. Also anything else you know that causes you to have gas.
Arlene, pouchitis will definitely make sleeping through the night impossible. As soon as you empty the pouch, it feels full again (although it's not). Flagyl worked for me but I HATE that stuff. More recently a naturopath put me on Mycostat instead and it worked too. With either one, within a day or two you'll begin to feel some relief.
