Hopefully you have the answers to your questions now, xchocoholic. When the book isn't free it is still ridiculously cheap! I can see how it would be overwhelming to an ME newbie, but one thing that it might still be good for would be the keyword search facility, in which you could, for example, search for words relating to various symptoms. ME has such a bewildering and changing range of symptoms that it is common for people to keep thinking they have something different from, or as well as, ME, myself included. Finding your symptom in this book as an ME symptom could save you lots of exhausting and frustrating trips to the doctor, who will probably not realise that the symptom is 'just' part of your ME. It is a collection of evidence about ME, with a good number of scientific references, so even for people without the scientific expertise to understand the source material, they can be reassured that the stuff in the book is based on evidence.
