Sorry to hear you're not doing well. Like you, I went on Imuran thinking it would put in remission and it didn't. I started Remicade last April. I've been doing really well since. I had a partial obstruction and it seems to have taken care of it. I wish I would have started it a long time ago instead of messing with Imuran, Pentasa and Pred. It's scary to think about at first, but really it's a piece of cake!
Good luck to you!
