I'd be careful about spending a bunch of money with 'brain state' therapies. The developer is very careful about how they promote and explain it. It is an FDA exempt therapy approved only to enhance relaxation. The predetermined 'program' of multiple sessions is often a give away that it is designed for money first and patient second.

I use music to help my brain relax and restore itself. I have found a few music cd's and dvd's that can put me into a relaxed sleep within 10 minutes. I wake up refreshed and feeling alive. Maybe I have found my own version of brain state balancing.
