Put simply, hypnotherapy is a method of speaking to the inner-most part of your mind - your subconscious - to eliminate old habits and behaviors and to generate new, beneficial behaviors.
Hypnotherapy has been successfully used by millions to lose weight, quit smoking, improve memory, become more successful and so much more. Hypnosis has also been used as a complete anesthesia, in both childbirth and surgery, that uses absolutely no chemicals, and so has no side-effects.
Hypnotherapy — the clinical use of hypnosis — has been approved by the American Medical Association since 1958, and the American Dental Association and the American Psychological Association, shortly therafter. It has been used in clinical settings for well over 150 years, around the world.
