My son had UC, now J pouch, then developed Crohns as well. He is doing well on Pentasa, 3000mg per day. He also takes the PB8 probiotic, which I found recommended elsewhere. It's all individual though. I agree with other posters that you are not in this alone. We tried many different things before we pulled some advice from here, some from there, and ended up with a plan that is working for him for the moment. Know also, and be patient with, the fact that there is no final solution. Hang in there.
