I agree, it is very difficult to come off prednosone.
The trick is to get the 1mg bottle and to come down 1mg a week. Day 3 will always give you a flare, but you have to get through this day by not doing too much, or maybe take another pain killer. Day 4, 5, 6, 7 should improve the situation. Then reduce another 1mg and repeat the procedure until you find your limit. I have managed to get down to 2mgs on occassions doing this. I have been on preg. for 12 years now. It is at 2mgs, all the side effects dissappear.
Diet and exercise do help with the pregnosone blues.
Take care and good wishes
