I am very impressed with this book. Traditionally I have steered clear of anything with a hint of self-help about it but, after months of disturbed sleep, I'd had enough. I feel that it's given great value for money - it adopts a friendly concise approach, enabling the reader to understand with ease how insomnia occurs and what you can do about it (rather than being uber-technical). I really like that it's written in a relaxed and accessible way, and although I'm still practising the exercises in the book, my sleep has noticeably improved.
