After consuming 27,000 mg of Predisone in one year, I also found it hard to taper off. I began dropping from 20 mg to 10 mg in one jump and found it didn't work. I went back to 20 briefly, then started reduction at 1 mg per month. That went OK until I got down to 3 mg and got a flare-up. Went back to 5 mg and tapered to one mg at which time my Dr. suggested going to 1/2 mg for another month before stopping. I have not had any problem now at zero for the past month so I feel I have finally made it off Prednisone for good.
