Just passing through this board again so I figured I'd give an update, though there's no real news.
I took a spill last week and injured my hand, so I won't type much. The fall was probably related to ongoing leg balance/stiffness/weakness issues, but I can't yet make a clear case, to myself or to a doctor, that my legs are worse than they have been since last July, the approximate end of my last relapse. I'm still walking my dog daily. So, ten months into rituximab, i should probably be seen as celebrating ~7 months relapse free. No improvement either, and I continue with the supplements noted above.
I get healthcare through Kaiser in CA. My neuro was resistant to putting me on rituximab, presumably b/c it was an off-label prescription. She had wanted to get me on the ocrelizumab trial instead. When I first suggested rituximab she was hostile to the idea, but I think she began to warm to it when I pointed her towards the frankly disgusting business coverage of why Genetech is pushing ocrelizumab instead of rituximab for MS. (http://neuroimmunology.wordpress.com/2011/03/27/the-shameful-story-of-rituximab-in-multiple-sclerosis/
.) Then when she put me on gilenya and my heart slowed to 30 bpm overnight in the telemetry ward of Kaiser Hospital, I think she finally felt guilty enough to prescribe me the best available drug, even if it was off-label. So probably not a path that others can hope to replicate in terms of getting access to the drug, but that's my story, take from it what you will.
