Here's the link to the LDN thread on the MS Forum:

I've taken LDN for a little over a year and it's been a Godsend for me. It took me a while to titrate up to the 4.5 mg dose but I'm there now and wouldn't be without it. Seriously, I took the standard Interferons that are prescribed for MS but they just made me feel worse than I already did. I finally tried LDN and have never looked back.
