Prednisone sucks, but it works. If you can do it for shorter, it can be a miracle drug.
The first time I was on prednisone, I was able to do a slightly different taper and had great luck:
40Mg for 4 days
30Mg for 3 days
20Mg for 2 days
10Mg for 1 week
The side effects were nasty but it was short-lived and kicked off a period of remission that lasted 3 years. Totally worth it.
THIS time.... prednisone worked but I flare every time I try to go under 20mg. I had a different doctor who did not taper me as fast and I became dependent on it. I've been stuck on it now for 7 months, and the side effects are horrific.
So, I'd say to call your doc and see if you can use a faster taper. Also, be prepped with a sleeping pill because you probably won't sleep without one the first few nights.
