Welcome Lori.. I've been on LDN for over 10 years now, after trying
Avonex then Copaxone. The only thing they say you shouldn't take
LDN with, is narcotic pain killers, because the LDN may cut down the
power of the narcotic.

Besides what Erika mentions, I find that it keeps my MS on a plateau
and I've not progressed in disability, in many years. I am also SPMS
and use a scooter to get around. Don't walk much anymore. I chose
to stop walking, after DH died and I was falling and could no longer,
get myself up.
