I say try, you can always quit. No "what ifs"to contend with. Doc. said try a DMD, I did Rebif, no bad side effects but didn't hekp me (PPMS, so no big surprise.) Tried Novantrone because "maybe" it would help, threw up, lost a few hairs, but it didn't work, but I tried You're in charge, you know better. Listen, but make your own decisions. Seeing new neuro, will ask for LDN. If he's not open to it, bet my PCP will prescribe it for me. Then I'll try. Know some successes, know some it did nothing for. But I don't know what it will do with me.
