Hey, it's at a pretty steep price but I recently found a product that helps with these symptoms. RLS is often a result of improper circulation, which causes blood pooling in the legs and feet. This can cause fatigue, RLS, cold hands and feet, dizziness etc.
This little research group on FB has developed something called the HeartPartner to help alleviate these symptoms and fix the underlying problem. It's pretty interesting technology; all you have to do is put your feet on the device and these unique vibrations go out and stimulate these nerves at the bottom of the feet, stimulating blood flow. They get more technical about it on their website but this is my layman's version ahaha.
Anyway if you're interested this is their website: sonostics.com/
And this is their Facebook: facebook.com/sonosticsinc/
