while I don't think that having low b12 means that I don't have MS (b12 deficiency is often misdiagnosed as MS), I'm looking at a list of symptoms for b12 deficiency, and one symptom really stands out.

Premature graying of hair.

I've been going gray since I was 17yrs old. For some reason, seeing that on a list of symptoms for b12 deficiency, it just really stands out for me. Tinnitus is another one that makes me go "hmmmm...." too. (had tinnitus for as long as I can remember).

I'm pretty sure I still have MS, I just also happen to be extremely low on the b12. I think the low b12 is why the stupid MS has been so freaking annoying lately. Maybe the MS will let up a little bit if I keep throwing some b12 and other assorted vitamins at it.
