Hope you don't get tired of me always posting here and asking questions. It's just the best site for information I know of. My neurologist prescribed Amantadine for MS related fatigue, but I've been afraid to take it because of the possibility of insomnia which I can't tolerate because of restless legs. But the fatigue is just getting so bad. Do any of you take it for fatigue? Does it cause insomnia? To top it off I also read that it's helpful for RLS. Too much for me to take in!
