Cindy, first let me tell you I am completely biased on this subject.
I was steroid dependent for four years. Couldn't get off them without getting so sick I could barely function, yet wasn't completely in remission even with them. Colazal helped, Imuran helped, but all three together just kept me functioning. I ended up with a lot of bad side effects related to long-term steroid use.
In February of 2006 I started on Remicade. By May I was in the best shape I've been in since diagnosed. I still have to take my Colazal and Imuran, but I'm now in a complete remisssion based on both my symptoms and colonoscopy.
Remicade does have some scary-sounding side effects, too. So far, I've done okay. I've had one cold since being on the Remi and no other infections at all. I do sometimes worry about the slight increase in the rates of lymphoma with it, but I've decided I'd rather deal with that risk than with a life of 20 trips to the bathroom each day, pain and bleeding and constant exhaustion.
Remember that this is only one person's story, and there are others who have had different experiences. I hope you'll hear from a lot of people about this so you can have more information when making your decision.
Good luck, and I hope you feel much better soon.
