I don't think there's any such thing as a "normal" taper. Your doctor will dose you according to the severity of your condition. The last time I was on pred, I was started at 40 mg. After a week, I reduced by 5mg and continued to do so each week until I was off of it. That's a relatively fast taper, but my flare was mild and I do alot of other things - dietary manipulations and supplements that reduce my need for meds.
I'd highly recommend you check out Coping With Prednisone: It May Work Miracles, but How Do You Handle the Side-Effects?
