Water.

I drink plenty of water, Mike, but I think you probably drink more. Everybody absorbs water a bit differently with a J-pouch. Some folks do fine with moderate amounts of water, and at the other extreme some need plenty of rehydration solution every day. Some folks have to sip and other can guzzle it down. The most reliable indicator of good hydration is light-colored urine. Follks who defecate every time they pee may have more trouble observing their urine. FWIW, I've found that a full bladder sometimes feels like I have a full pouch, too, but once I've peed the pouch sensations often go away for quite a while. It's also a good chance to practice very valuable muscle control.

Whatever works for you is the right amount of hydration. I know I tend to be on the dry side, but I mostly drink when thirsty and like to eat a lot of "wet" foods (soups, fruits, yogurt, etc). But really, whatever keeps you away from the doctor is correct!
