"Insomnia - 50 things to do" is an excellent book! Almost like a "to do" list, except it is about 200 pages. The explanations are short, dense, but still easy to understand, and deep enough to cover all the important aspects of sleeping, the contributing factors, and the different treatment options chapter by chapter. I was surprise, how fast I got through this book. (I have to admit, it wasn't my first book I've read on insomnia.) It is an excellent summary of all the things I've ever read, hear or seen about insomnia so far. After finished reading the book it was easy to look up certain parts to reread, and it was easy to create a plan, the list of things to change in my lifestyle, to get better sleep. I think this book can be helpful for others also (with or without sleeping problems) in self-education, and in the work of improving the quality of sleep and the quality of life.
