Hemi Sync

I saw a program about near death experiences, and they discussed Hemi Sync. It's a system developed by the Monroe Institute using sound waves to wake up areas of the brain that we wouldn't normally tap into. Some people use it as a form of self-hypnosis to help them with pain, addiction etc. I want to try it out for kicks. I think it is possible for me to download it. Once I start using it, I will put it into my schedule and tell you how it affected me.
