I've been using light therapy to treat my RLS for 18 months now and it's been working great. I use it for 30 minutes a night every night and if I use it faithfully I never have a problem. There's been a few times I've gone on a trip for over a week and forgot to bring my device and my RLS came back but after I get back on it it works! I bought it from this company here in Canada called Tranquilmed. Has anybody else found success with using light to treat RLS?
