Restless Leg Syndrome?

I am a lady in my 60's and have RLS. I will NOT take prescription drugs for the condition. Has anyone found relief with over the counter dietary supplements? For example..Magnesium, Calcium, Zinc, Glucosamine, chondroitin. Or some other type of vitamin? Any suggestions will be greatly appreciated. I don't want to take prescription drugs as they seem to have way too many side effects.
