I have been working with the Holosync program on again, off again for over ten years. I was one of their earlier customers and back then you could get Bill himself on the phone. I must have talked to him accumulatively for a few hours at least back when I started the program. Honestly he really seems to have grown a lot from using the program himself over these years. He really seemed to have a lot more issues back then - I might even say that he came across as a bit of an ***hole, but I still liked him.
The CDs I currently work with are at the end of Awakening Level 3. I really like the Centerpointe products - Quietude and Oasis are great for working / studying. I also have used their silent subliminal series pretty consistently over the years. I find that they fit well with just about any other program that I have come across.
