PredniSONE and ba

On the stuff for 7 weeks. Started at 60 mg for 4 wks now at 30mg for a few days then tapering to 5 in a few weeks. Moon face, insomnia, lots of food, seem to be in some kind of "zone" most of the time. It is a good and ba d durg but it is keeping me out of the hospital. Quit smoking in April (after 30 yrs). Started with chills and fever (up to 104) then pericarditis, the pyoderma ganrenosum. After tons of tests (blood, bone scan, bone marrow,cat scans, mri's,cultures, etc.) doctors can not come up with diagnosis. Scared to get off the drug but will.
