The only good story I have is, the first time I had IVSM, was in the hospital and about 2 weeks after, with some PT, I went back into remission.
However, it was short lived and a few months later, I had to do IVSM again and it didn't work....AT ALL.
I hated it the first time but even more the second time. I even tried it a third time, glutten for punishment that I was, and it did NOT work, again.

No more roids for me.
I had segwayed into SPMS....and 'roids do not work on SPMSers (period, paragraph). I don't care what your Doc or anyone else says.
I still think your best bet is Paxil or some other dirty little SSRI.
