I don't think the Imuran is doing a darn thing for you. At that dose for 5 or 6 months you should have gotten a lot better, not worse. It is a very dangerous drug to take if it isn't even going to do anything. I would start back up on the pred. Your plan on that sounds good to me. I would seriously think about talking to the doctor of dumping Imuran.
