I hope you have some luck with the cortifoam!
I'm definitely doing better with my flare since I started back on it. It's usually really works for me, so I hope you have the same good results.
I really, really recommend acupuncture and/or hypnotherapy, if you can find the right practitioners. I think the hypnotherapy can be great. You learn how to relax your body in such a deep way. It's something that you can really benefit from forever. There are studies (out of UNC-Chapell Hill and also from the UK, I don't know where) that proved that hypnotherapy helped sufferers of IBS. They haven't, as far as I know, done studies with colitis patients, but from my own experience, I would assume the studies would show the same good results.
I think you should try it! Let us know how it goes.
