I've read every book there is on insomnia, and most are written by authors who have never experienced it and offer lame and obvious 'advice'. This book is the ONLY one I've read that truly understands what it is like to have chronic insomnia (not just a bad couple of nights!). This gives the book immense credibility over any others on the market. I don't know if the author is himself an insomniac or just has an outstanding understanding of what it is like. Doesn't matter - this book is different, and that is what makes it stand out.
The CBT program itself is very easy and very good - sticking to the 6 week timeframe and tasks (i.e not just reading the book cover to cover..!) is crucial. I followed the program religiously, and can report that after 20+ years of insomnia of varying intensity, it was VERY successful. And crucially it still is - 1 year on.
OK, I'm not an expert sleeper, but as the book says, I probably never will be. Some people are good at maths - some are good at sleeping. But gone are the 3am / 5am shockers, and my 'sleep efficiency' (how quickly you nod off) is much much improved.
This is a book for chronic insomniacs. You know who you are! Get it - you won't regret it, and you WILL sleep better. I give it full marks.
