Friend swears by Paul McKenna and just listens again to the CD when cravings hit. However, I must say that this friend was very motivated to quit and strongly believed that hypnosis would work for him and that McKenna would be the right person for the job. Without these firm beliefs, your mileage may vary.
Oswald, kudos to you for fighting off the cravings for 10 years. That sounds really difficult! Good luck.
