I hesitate to respond to this because I don't know if it will help you. I have RLS and have since I can first remember. My father and his mother also had it since childhood. I had wrestles legs just last night and coincidently because of a recent miscarriage had to have my blood and iron tested. I was not deficient. I think it is something that can run in families and may not be related to deficiencies at all. Mine does not keep me awake, but when I get it, i just have to go do bed because it is a sign to me that I am tired. I wish I had some actual advice, I've just always lived with it and have never sought medical attention for it. Since it is something thats always been around, but only recently has been considered a legitimate condition, I just don't think they know much about what causes it or how to treat it.
