The best option for you is to interview several qualified hypnotherapists asking the questions we recommend in the "Finding a Qualified Hypnotherapist" section. Then once you've narrowed down your search, book a 30 minute consultation (either in person or on the phone) with the one or two you like the best. The consultation will give the hypnotherapist a good understanding of your issue and will better be able to help you determine the number of sessions required to achieve your goal.
