I recently purchased the self hypnosis/subliminal CD from wheeler tech that is geared towards pool players. All I hear on the thing is the sound of the ocean. I am an employee in a medical center and pick the brains of some of the shrinks on the staff while working on their equipment. They told me that self hypnosis is a valid method of enabling a person to perform to the best of their ability or to stay focused on the task at hand. Has anyone had any experience with the CD that wheeler tech sells and if so what is your opinion. Thanks for any feedback.
