I stopped taking it when I started on the Copaxone, my Dr. sure if there would be a conflict between the B-12, LDN, also gama globulin shots. I felt great on those but stopped when I let the Neuro talk me into trying the Copaxone. I started up on the B-12 again 2 mo. after stopping the Coppaxone. Now I think I have developed an ammunity to it so I decided to stop for a few months to see what happens.because the fatigue has hit pretty hard again about 4 months ago.
Burden
Going to the Dr. on a monthly basis became a challange.
