Cushing syndrome

Hi! there,

I am on 50mg a day of PREDNISOLONE for Chronic Inflammatory Demylinating Polynueropothy. I have quite bad Cushing Syndrome due to the high dose of steroids. I have been taking this dose for four months, I started on 60mg. I was also having IV IMMUNOGLBULIN. My DR has now stopped this, as he feels the steroids are doing their job. I am doing really well. My question is how quickly will the Cushing syndrome go when I come off the steroids? my Dr hopes to start withdrawl in July. I am not coping to well with the physical changes, and worried I will never return to my normal self.
Thanks,
Ruth
