Linda (Orlando, FL) on 02/23/2007:
I have taken potassium supplements for many years (plus iron and calcium) to control my RLS symptoms. It took me a while to find the right balance of supplements, but my RLS rarely keeps me from falling asleep. It still bothers me on long car trips or in a long movie if I'm tired.
I had a sleep study done a couple of years ago, and the doctor remarked at how much leg movement I have in my sleep (even with taking the supplements). He indicated that RLS is associated with low iron. So, I increased my iron a little, and the symptoms improved. I know, however, that the potassium helps because if I run out of it my legs are "dancing" within a couple of days.
