I have been suffering from RLS for many years. I used lots of different technique such as yoga, meditation, hot water massage etc, but all gave some temporary solution, but I never got permanent relief from this syndrome.
I was aware of the urine therapy from childhood as I have seen some of the rural tribals those used this therapy because they were not exposed fully to the modern medicine, but I was hesitant to use this therapy because of some psychological barrier.
Finally I decided to use this therapy when I was not able to tolerate RLS anymore. I got relief in couple of days, and I am able to sleep well now and I am free from RLS completely.
There are books in amazon or you can google it. It is very simple therapy.
