Hey AndyMan,
I hope everything goes well or went well. I wanted to offer my info in regards to Imuran. I had a hard time with that medicin. It seemed to work pretty well (I got me down on the Prednisone), but I had terrible stomach problems with Imuran. I took 50mg/day. I lost hair - but not as bad as before, although I had a brush full of loose hair every time I brushed it. SUCKS!!! But... when I started getting heart pains the MDs took me off Imuran immediately. My stomach is slowly easing up again, but Imuran was very hard on me.
Best of luck to you.
