Good, I'm glad the treatments are helping you. Cellcept can take longer to kick in than Pred but it is hard to tell which is making you better. Sometimes doctors only try one drug at a time to see if it's working. Otherwise, it can be hard to tell which one is better for you.
Don't forget that you should be on calcium and Vitamin D3 (at the same time) while on Pred. Don't take that at the same time as any vitamin C, in tablet form or via food like citrus (it won't absorb as well). And since Pred is an antiprostaglandin, having good prostaglandins daily like walnuts, flax oil, olive oil, etc. is a good idea. Run anything by your primary doctor too.
I'm glad you're still "squirrley" because attitude helps so much with MG.
