myasthenia gravis
"I was on Imuran for about 20 years for MG. but it blood tests begin to show liver damage. I went to 20 MG of prednisone a few months until it was reduced to 10 MG, then 5 MG. I relapsed again and increased to 60 MG by the end of 2014. Began taking  400MG Celcept while decreasing prednisone. Happily off prednisone October 2015, with no signs of MG. Prednisone destroys protein so I was weak and had gained 25 pounds. January 2016, still on cellcept and back to normal weight. However am weak, ache, and sleep little. These are possible side affects of cellcept. And will be looking for a solution. On a daily basis it beats the heck out of prednisone."
