Um, your doctor is JUST NOW starting to worry about
getting you off pred?! After you've been on it for 10 years?!
Holycrapballs.
I think your first step should be to find a new GI, quite honestly.
ETA that I'm not sure where 10 years came from.....I'm a bit sleep deprived b/c my six month old hasn't been sleeping well lately. But still, you've been on it FAR too long!
