I had the same symptoms, plus anemia; I've been on Pred since April 2006 and the symptoms started when I got down to 5 mg of Pred every other day. I've been treated for the anemia and had another Remicade infusion. I am going back to the GI onthe 21st and hopefully he'll start me weaning again, this time successfully. If I I can't get off the Pred apparently it's time to seriously consider surgery.
I don't know how it can mentally addictive -- I can't wait to be through with the Prednisone. The only side effect of the wean I DIDN'T mind was the lack of appetite. The weight I gained on the Pred quickly came off.
