Since the publication of its first edition in April 2014, Dr Myhill’s guide to understanding and overcoming CFS/ME has become a must-read for sufferers from this poorly understood condition. As one example of the nearly 300 5-star reviewers on Amazon says: ‘Extremely useful, well written, concepts well explained, absolutely great investment of money and time in reading it.’ In the seven years since the second edition was published (January 2017) both new research and new clinical findings have thrown further light onto a condition that for sufferers is life-stopping but for many doctors is ‘all in the mind’. Most recently, the UK’s NICE guidelines have been updated and Long Covid has changed mainstream perceptions of post-viral fatigue, while Dr Myhill has looked further beyond mainstream medicine into often-ignored more traditional treatments including methylene blue and DMSO. Dr Myhill, supported by expert patient Craig Robinson, has fully rewritten and updated her book to include new insights throughout and new chapters on the PK diet, photodynamic therapy, micro-immunotherapy, ME and Long Covid, and the politics of CFS and ME.
