Has anyone had experience with Jakafi?

I was diagnosed with polycythemia November 23, although it is likely I had it for a significant period prior. I tolerated the hydrea well for three months, then became quite ill as a reaction to the hydrea. After trying to "restart" several times, the same reaction occurred. My oncologist then started me on Jakafi about 10 days ago and, so far, no side effects as I am tolerating the medication well. If all goes well, this is a medication that makes you feel as if you are cured as it controls HCT, WBC, platelets, and iron levels, without phlebotomy. Please advise if you have been on Jakafi and what your experience has been.
