Thanks all. Note that I have yet to be diagnosed with MS. All I've been told so far is that I've had a clinically isolated syndrome. I think I'm going to look into an MS Center near me to see if they can help diagnose/rule out.

I was prescribed Gabapentin for my twitches & it worked a treat. Like you I would have to keep fidgeting & ultimately get up for hours at a time til it stopped. Your MS nurse/neurologist will start you on a low dose & build it up until they find a level that works for you. It also worked on the neuropatholgical pain I got in my legs & my poor aching back
