In extension to kevinwright200958 post today about a relationship between climate and strength of symptoms, I thought I'd post an idea that occurred to me this morning, i.e., whether there's a connection between body weight and rls severity. There probably isn't, but it gave me an impetus to shed weight and see what happened.
When I was young by the way, and still suffered from rls, I probably weighed no more than 70kg. My ma-in-law said I looked like a skeleton back in the early '70s, and rls was just as bad back then.
But it's an idea.
