I am mentioning again, as I have somewhere in the past on here, the helpfulness of calcium for RLS. It doe not take it away the fact that a person has RLW, but what it does is to calm the nerves themselves. (Magnesium also helps with this.) My chiropractor, as well as other sources, have recommended this.
One of the better types is calcium citrate, as it is easily absorbed, as compared to some of the other sources of calcium. I take @ 1,500 mg per day, divided up into two doses, as one's body can only handle lesser amounts at a time (I read.)
It seems to help by calming the nerves, so as to make them much less irritated, and thus, the RLS much less disturbing. Give it a try!
