For quote some time now, in the evening I get odd involuntary neck movements, a slight shake of the head from side to side. It's a bit disconcerting I have to say. I wondered if it could be related to rls. Has anyone had anything similar? I do get rls in my shoulders, arms, hands, wrists, legs and knees when I'm very tired. Fortunately for me I don't suffer every day since increasing my magnesium.
