Is it from the Prednisone? When I was on that last year the same thing happened - as I was weaned off it the night sweats and moon face and appetite subsided. The best thing that I did for myself was get as much exercise as I could, even if it was walking around the house, lots of water and very VERY little sodium. Good luck! It will all subside eventually, I now it's hard now but will get better!!! :)
