I was prescribed Prednisone for 10 days initially and then degreasing dosage for a long time. 9mg daily for 14 days, then 8mg for 14 days, then 7mg for 14 days and so on until I was off the stuff. This seems to be a long time for me. I have night sweats, insomnia, fatigue, lack of concentration, and lack of ambition. I am a 70 year old male prostate cancer survivor. I am also taking Toprol 50mg daily. Will all of the side effects go away eventually? Very tired old man.
