I have had good luck with Imuran too! I think it's the only thing that allowed me to get off of pred after nine months of the evil stuff. I really noticed the difference when I was able to taper my pred under 20mg - which was probably at 3-4 months. Previously, once I got to that point the flares ALWAYS came back.
The only side effect I can tell is from the Imuran for sure is dryer skin. Nothing some lotion can't fix :) Oh and the most intense, vivid, nonsensical dreams you can imagine! They can be pretty wild - but always STRANGE.
