Does anyone have the side effect of reduced sensation of smell and taste? I just got off of 7 days of 20 mg. Prednisone twice a day for severe poison ivy. I've always had the reducing dosages before but went to a new young doctor who said this was better. I experienced extreme insomnia for several nights. Last night I slept better, but today I'm feeling dizzy and have slight soreness in my back and neck. I'm really hoping this all clears up soon since my son is getting married in 12 days and I don't want to be dizzy and moon-faced at the wedding.
