Hi,
My Myasthenia was pretty bad in 2006.. I tried Mestinon but it did not work very well and it tore up my stomach at high doses. I was put on Cellcept and I started to do much better at about 3 months. It has its side effects, but being able to move again was pretty nice. I am unable to take prednisone.... so I was happy the Cellcept worked.
Good Luck
Deb
