Yesterday I discovered that doing something with my hands helped with situational anxiety. I went to a beading class and made two great necklaces. While I was actually, physically doing something with my hands - picking out the beads from the store, arranging the beads on my tray, stringing them, "crimping" (finishing), I was basically OK. As soon as I stopped doing something with my hands, my situational anxiety would come back.

If it works so well for anxiety, it might work for restlessness as well.

I posted about it on the Anxiety forum, and others have had similar experiences and suppose that it might be grounding, that it might be the hand-brain connection, but I also think that the relief comes from the sense of purpose - I was actually doing something useful.
