There are some things you can do to improve your situation. Many pouchers find that eating Metamucil wafers helps to absorb excess liquid. Try eating two before your meal. It seems as if you only want to sporadically take the imodium; lots of pouchers find that they need to take it regularly; there's nothing wrong or dangerous using it. Your best resource for help is at www.j-pouch.org That site has over 6000 members who have had the surgery and they might be able to give you some advice. I don't have the issues you have so I am not the best person to respond.
