Hi. I'm GF. I'm 43 years old and i've been dealing with MS since 1999. Currently, I take Rebif and supplement with 5000IU of vitamin D3 (among other vitamins) as safely as possible. My neurologist claims i'm still relapsing/remitting, but lately, i'm not sure--or if my problems are just a series of exacerbations. I'm glad there's a place where so much MS information in available, since other sites usually post the standard textbook definition of the disease.
