I'm also new to this site, but not to MG and Imuran. I've had MG since 1969 and have been on Imuran since 1995. It's been the greatist thing and changed my life! I still use 5mg Prednisone daily and 60 mg Mestinon as needed. I also have Rheumotoid, but the Imuran has kept it well under control. LetaSu
