Your GI is crazy, that's way to fast of a taper. And honestly, being on pred for 2 1/2 months isn't that long either! I understand he wants to get you off, but in general, the thinking is "stay the course" at a higher dose until you are symptom free for a month or so, then taper ever so slowly. My tapers always lasted forever, like months & months & months. 5 mgs a week or 2 here & there, then slower & slower, 2.5 mgs a week or 2, etc. It sucked! But- i was able to get off it ok, with the help of Remicade. It's unebelievable that such a low dose, like 2.5mgs, can actually do something, but it does! Can you get a 2nd opinion?
