myasthenia gravis
"I have been taking Cellcept or Mofetil for I think 10 years.  I take no Prednesone or Mestinone.  I am nearly symptom free.  After I had taken Cellcept for about a year.  I thought I was cured and quit taking the drug.  A few months I crashed.  It took 6 months to recover.  I find Cellcept or generic far more preferable than Prednisone.  Prednisone makes me crazy and can't sleep.  Cellcept takes a while to work. That is  I think because it has to get into the marrow of the bones where the B cells make the antibodies that attack neurotransmitters.  

I am extremely upset that medicare is trying to take this away.  They just sent me a letter denying coverage.  A crash from this drug nearly put me in the hospital. The drug studies appear stupid"
