How Long Will The Rebound Effects Last After Steroid Withdrawal?

I'm going cold Turkey on the use of topical steroids with the help of a good (new) dermatologist. I've been a daily user since early childhood I'm now 43. I've been perscribed Doxycycline to help with the process. How long are the rebound effects likely to last I'm pretty sore right now about two weeks in. I'm still taking 10mg of prednisone daily and 100mg Azathioprine
