First off, it is NOT smart to come of high doses of prednisone as some people here are doing. If you come off from a high dose, you can develope something called adrenal insufficency--which can put you in serious danger, and the side effects will double.
I'm on prednisone, 80mg a day (and i'm only 110 pounds), and the side effects are awful. However, if you don't like the side effects of prednisone, or how you're doctor is handling it--change doctors. Prednisone is not a drug to play around with. Please be careful.
