I've had RLS of and on for years and it turns out to be related to fibromialga. do you have any tingling and/or burning in your hands and feet? It is most definately a mineral deficiency, magnesium, calsium, potasium but i think mainly magnesium. I take something called "Natural Calm" it's a type of magnisium supplyment that is very relaxing, i highly recomend it. Quinine, that's in tonic water may help also, this is what my mother used and it worked well for her. Good luck.
