Wow I feel like I asked that question. Im on perdizone for about a month all ive noticed is water retention and about 10 xtra lbs. I would fight it off if possible. I agree that MG diagnosas may be an educated guess. My results all come back to the contrary of what they are looking for. I was diagnosed in 2007 I went into remission and actually figured the docs were wrong. But it came back with a vegeance 5 years later
