If you're unable to come for a personal consultation you may like to try one of our self-help books. All of our books, which you can find listed in the self-help books section of the NHAS shop, are based on 17 years research and clinical experience at the NHAS. Whichever one you choose will provide you with the information you need in order to overcome your symptoms. All our advice is based on published medical papers which are referenced at the end of the book for the technically minded. Whilst our books contain details of our programme and have been designed as a comprehensive self-help guide, it is not uncommon for people suffering severely with their symptoms to need closer attention. If you feel that you are 'straying' from the recommendations in the book, you can enrol on one of the following personalised programmes.
