Here is a link to the jpouch group. Lots and lots of information there. Check out the forum too.www.j-pouch.org/Whatis.html
What you are experiencing is normal. You train your pouch by holding your bowel movement as long as possible as often as possible. Eventually over time (3 months - 1 year) your pouch will stretch and get used to holding stool and you will go less often.
If you find you are going all the time - call your Doctor. They can give you a prescript
ion for Lomitol or may suggest Immodium to help with the frequency.
Semi-incontinence is also very normal at this stage.
I just had my take down 12 days ago, so I am having the same kinds of problems. I am on Lomotil now and things are better. I am still up 5-7 times per night and going 16-20 times per day, but it is mostly formed and more comfortable to pass.
Patience and time.
