As a supplement to the book, Self-Hypnosis, Drs. Alman and Lambrou have created the Audio Hypnosis Library, a series of audiotapes designed to assist both the professional and the lay person in utilizing the self-hypnosis techniques discussed in their book. The tapes (each about 60 minutes) are designed to help assert control over a specific problem..by accessing the strength of the unconscious..using the uniquely power tool for hypnosis.
