Not sure if anyone else has tried this but, I have found something that sometimes works for me.
I have suffered with RLS since I was pregnant with my first child, eighteen years ago. I believe mine to come on when I am hot, tired and resting.
I have found by chance that when I am in bed if I put ear phones in and listen to my music rather loud that my mind is concentrating on the music so much and I am so tired I fall asleep. Its weird but somehow it works a lot for me.
I am often woke up by the earphones falling out but it doesn't wake me up enough for the RLS to return as I fall straight back asleep.
Obviously I try to listen to music that isn't too energetic but you need something with a beat or if it is too relaxing it might not work?
