I've had RLS since I was 13. I only found out it was a recognised medical condition when my wife sent me to a sleep clinic because she thought I snored too much and had sleep apnea. Medical opinion on those two points was that I didn't snore much (diagnosis disputed on the home front), and didn't have apnea. I am, however, receiving treatment for RLS - miraprexin (also used on Parkinsons Disease). Its significantly reduced my symptoms, although I do get periodic bouts.
Prior to treatment exercise was the main method to relieve the fidgets, now long events are likely to trigger an episode.
