Yeah, he said it's either the 6mp or I'm not absorbing stuff. We're betting on the 6MP, since I'm not losing a ton of weight. I guess I'll see in a few months 
Imuran = azathioprine, yes. I was on that a couple of years ago but it gave me wicked nausea. So I switched to 6MP. Wasn't as bad. I've also been on "the cort" as I call it. It's my band aid steroid when things get bad. I take it for 3-4 months about once a year. Nowhere near as bad as prednisone
I hope the Imuran treats you well.
