Wow, that is my exact beginning story. My PCP started me on 20. I had the breakthrough pain in the middle of the night. My PCP ok'd the split, at my suggestion (because I learned it was an option from this forum:), but my body was telling me also. When I got to the Rheumatologist, a month later , she said she was ok with the split, said whatever works. I can't believe some docs are so rigid in their practice patterns. I would be looking also if my doc wouldn't listen to what I was saying.
I will have to research more on that 10% taper schedule. It makes sense, I know it needs to be done slowly, I know the relationship to the adrenal glands, but I can't imagine being on Prednisone another 10 months, yuk! I know, I know, I can't hurry this but I want to....
