I tapered down Prednisone in December, meaning that I was done tapering in December and quit taking it. I lost my moonface in the beginning of April ... that's a mighty long time. Hope you will not have the cheeks for the rest of the year.
On a positive note, I had the most beautiful skin on Pred. It was flawless and smooth and gorgeous. Now I have zits and dryness and redness thanks to 6MP. Boo! But I chose that over Pred of course.
Hang on in there and all the best for you!
