I will keep this short, so if any one wants to ask me more about this they can do so. I posted some time ago about approaching RLS from the viewpoint of fixing my sleep problems first, not the RLS. And that is what I have been doing. After more than 6 years of having great difficulty sleeping, with RLS becoming often very bad, I seem to have gotten a really good hold on my sleeping disorder by concentrating on that, AND at the same time my RLS has just settled itself down to being almost non-existent. (Just a tiny flutter here and there.) I am now sleeping so well - deeply and with dream cycles, and if I do wake to use the bathroom, I can go back to sleep easily. I can get 8 hours of good, refreshing sleep.
In fact, on a recent trip 6 hours out of my time zone, I thought jetlag would really mess with my sleep, as it always had in the past. But I had very little jetlag and fell into the new time zone easily. Same with my return (except for one small glitch when I ran out of one very important supplement.)
So, I will reiterate that yes, RLS can cause problems with sleep, but attempting to fix the RLS may not be enough. One probably needs to fix the glands that are involved with the sleep disorder, as well. That is what I have been working on. With great success!
