Hi, Dunninator. When I had my colon I used a small footstool and it helped with elimination. But with my j pouch it does not seem to work. Maybe it is because the  j pouch is in a different position to how your colon and rectum used to be, I am not sure. If you look on the Internet for side views on the way a j pouch is positioned inside, it seems that leaning back gently toward the toilet tank, as if you were going to lean back to relax in your favourite armchair, helps straighten out the j pouch and things take its gravitational course!  Or sitting up very tall and straight on the toilet. At least that is what I have found. One day I was so exhausted I sort of leaned back to rest lightly on the toilet tank, and it was so helpful. Now I do this whenever I feel stopped up and I do NOT need to strain. Don't strain. Try leaning back. Or sitting up tall and straight. I hope this can help everyone avoid straining.

I'll echo everything winterberry has said, i have one but i didnt find it useful really at all. i had the same experience with leaning back though, curious, maybe i will try it more as i never commited to always doing it.
