Hypnosis is increasingly recognized as an effective treatment to (amongst others) lose weight, stop smoking and psychological issues. It is safe, simple and not scary or mysterious. The feeling during a hypnosis session is a bit like daydreaming and you will follow the experience. You'll find it a pleasant experience and that you remain completely in control.
With hypnosis your subconscious mind can be influenced by the hypnotist and the hypnotic suggestions that you may accept as a new reality. With only one or two sessions, important changes may be achieved.
