What has me worried is the word rebound.....That is different than just the disease caming back, when you stop a Med. Did you ever have a rebound headache? It's usually worse than the original headache.

What they are saying seems to be, that the MS comes back faster and more furious, after stopping TY than what your MS was like before TY.

It's just my experience, but my MS did not get worse after stopping Avonex or after stopping Copaxone....As a matter of fact, I felt much better after stopping Avonex and Copax made no difference at all.
