I have the same problem with water. It just runs right through me and takes anything I have eaten along with it. Sometimes with leakage. Drinking water just makes it too hard have any food in my pouch. I am totally open to the fasting idea (I've had pouch 26 years and been dehydrated all that time with several kidney stones passed and surgically removed.) The thing about the fasting idea is that I have been anorexic pretty much my whole life and would not even eat at all if I didn't have to. So there is no way I could convince my husband and family that I was fasting for the sake of a "pouch schedule". I do always stop drinking water or any dairy by 2-3pm everyday and stop everything by mouth by 7pm. I don't and never had any problems with having to get up in the night to go or leakage at night. I just wanted to comment and let you know you're not alone in the whole "cant drink water thing." And also the Kidney Stone thing. I'm sorry you are going through so many issues and I hope the fasting works out for you. I just want to say it was nice for me to hear someone having the same issues as myself. Best of luck to you.
