★★★★☆
If I can feel the restlessness creeping into my legs as the evening moves on, I'll take a spoonful of ACV in water. (Of course then I have to rinse my teeth off... too much acid.) But another thing that is helpful is HEAT, in the form of a hot water bottle between my legs. This is usually enough to keep me comfortable so that I can sleep without having to get out of bed and go get the vinegar. It must be because it relaxes my muscles. I've heard other people have success with sea salt, but I haven't found it makes a difference for me, and I already get plenty of sea salt/ Himalayan salt in my diet...
