Having recently been diagnosed with CFS I was eager to find out more information, since the doctor was very vague about it. This book has been a real eye opener and has taught me so much more than I expected. The book is really comprehensive and covers just about everything you'd need to know, and is also really practical. I haven't given it five stars because I have a few niggles.
Some of the advice and information focuses on 'evolution' and cavemen etc and this goes against my personal views. It felt a bit... We believe this in science so you have to as well. I also didn't like how the book seemed to demand that you don't have sleeps in the day and you make yourself exercise, that's to say, the tone felt a bit forceful in places. It's by no means a one size fits all illness.
Also in one of the later chapters it talked about recovery... But CFS is a chronic illness. I don't know how this works. When I first started reading, also, the book was kind of gun to the head, saying something on the lines of 'you are only allowed to read this book if you're diagnosed'. I thought that was a bit inappropriate. At the time I got it I hadn't been diagnosed, but thankfully I stuck with it. That note in the front could have lost me before I began.
All that being said, the book is, overall, really decent. My favourite part of the book personally was probably the inclusion of the life stories at the end of each section. It was so heartening to be able to connect to others when CFS can feel so isolating. I would recommend this if you have CFS, but to take certain advice, some of which seems more opinion than fact, with a pinch of salt.
