After five years of constant high doses of steroids, i am trying to cut down but i am getting light headed dizzy feelings. Doctor said its because i lack oxygen and get confused. I find it scary and wondered if anybody else felt this way coming down from 40 mg to now 15 mg. Doc said i would feel aweful.I think its making me depressed. Makes me feel like going back up on a higher dose. I look forward to any advice. thanks.
