Help!

I ran across some info on RLS by accident, and think I have it. I get very weird sensations in my arms, hands, legs, and feet. Last night the longest period of sleep I got was 20 minutes. I don't have the symptoms every night, but I have begun to dread going to bed. I briefly mentioned the weird symtoms to my doctor a few months ago, but we were talking about other problems, and this didn't get much attention. I will bring it up at my next appt. but would like to find out more. I have tried exercise, supplements, relaxation, and nothing works. At first, I thought I was losing my mind! Anyone have any info?
