Yup. I have had success with meditation, specifically hypnotherapy for IBS. There's an article on Healing Well about it:
I found that the research on hypnotherapy/meditation has been focused on IBS, so there's no real research yet to say that it can help someone with UC. But that doesn't mean that it can't. It just hasn't had the focus that IBS has had.
I found that the hypnotherapy really helped with urgency issues. Even years later, I can often relax my body enough so that I can walk, not run, panicked to the bathroom.
UC for the last ten years
Current Meds: 6MP since 2006, Cortifoam
Past Meds: You name it; I've tried it. (Asacol, Colazol, Pentasa, DiPentum, Rowasa, Canasa, Cortenema, sulfasalazine)
5ASA drugs don't work for me. Canasa seems to make me worse.
Alternative treatments I have had success with: Acupuncture, Hypnotherapy
