Be careful not to push it to much. I have learned from experience To go slow. I have been on Betaseron, Copaxone, Rebif, Tysabri and ow LDN. LDN is my last choice before chemo. I have had ms for 10-1/2 yrs. I'm still walking. I look like a drunk sometimes, but hey, that's ok. I can't walk far and I know my limitations now. I use to push it, and then I did more harm than good, so be careful. Excercise and work is good, just don't over do. I have learned the hard way. I'm not looking for LDN to "cure" me or turn back time, but it would be nice to stop things till a cure came along.
