So True, Virginia. By the time, the ABCRs were available for me, it was too late for much help. I did try Avonex and Copaxone but progressed to SPMS.
I wish I had had LDN before progressing to SPMS, but, as it is, LDN is keeping me pretty stable for the last 4 yrs. It does not go back and wipe out the nerve damage that has already been done, but I did improve some and haven't progressed in disability.
It is a personal choice, but looking into your options wouldn't hurt. MS is a progressive disease. I had "Benign" MS, with just one exacerbation, for 30 years. Since I was not having attacks, though, the ABCRs really wouldn't have helped, I guess?
A change in diet and keeping general good health and perhaps taking something like LDN may keep the monster at bay, while you are having no attacks.
Love and Good Luck,
