CellCept and prednisone

I am being treated with Cellcept (1000 mg in the morning and 1000 mg in the evening) for pemphigus vulgaris. Although I am post-menopausal, recently hot flashes have reappeared (yuck), and I am curious if they could be attributed to the Cellcept. I am also on Dapsone, Prednisone, and Valtrex my other main pemphigus medications). I have been taking Cellcept for about 2-1/2 years at this same dose.

I was just placed on Cellecept last week- 500 Mg 4 times a day-
for my autoimmune muscular myopathy- I was a body builder 6 months ago- now I can barely make it across the Target parking lot.
I am sure the myopathy is Statin induced as I was on Lipitor-)rather than Prednisone as my doctor said less side effects.
He said I should see improvement in about 6 weeks- is any body taking Cellcept for autoimmune disease?
Thank you.
PS; So far- side effects seem to be weakness- more shakiness-
