Nasty stuff that prednisone. I have an inner ear condition called Meniere's Disease that requires me to be on it once a year for 2-3 weeks. The first time I gained about 10 lbs. It was the weirdest thing....I had an uncontrollable urge to eat. Finally one night, as I was attacking a pint of ice cream, I came to my senses and realized something wasn't right. I asked around and found out that prednisone has that effect. I was pissed that the doctor didn't warn me. The last few times I resisted the urge to over eat and actually lost weight. Exercise helped me cope. I give a lot of credit to cycling. I can't imagine being on that stuff indefinitely. Best wishes.
