I've never tried it, Kelly, but you can read all about it here...

I know, you have to ramp up on it, much like you do LDN....up to a posible 40mg...although 30m seem to be the optimal dose for MSers. S.E.s..possible seisures at high doses, restlessness and diarhea ( may be avoided by ramping up).
Right now you can get the instant release oral tabs, but, as you will see, they are trialing the sustained release 10mg tabs.
Let me know if it works...maybe I'll add some to mine..
