Professional Stop Smoking Hypnotherapy Script For Professional Hypnotherapists: If you are just starting a practice then these scripts will interest you. Our clinics in London have a 95% success rate in helping our clients to stop smoking. We are publishing the two main scripts that we use, together with the pre-talk that we give every client; a total of over 30 pages. The initial session can run anywhere between 50 minutes and an hour and a half, depending how much preparation you intend to use. The main session is more focused on a brighter future while the backup session is more 'away motivation'.
