So it was all right before the part he start talking about self hypnosis, like as if doing these exercise can help relieve symptoms of anxiety and stress all that but the truth is that talking to oneself like that will just make you more anxious from a psychology prospective since the brain was constantly reminded of anxiety, it would just make things worse.Some other emotions such as anger would be necessary rather than joy alone, and the cause of sleep walking problem remain unknown so better consult a doctor rather than trying to self hypnosis,the same thing applied to tinnitus, it’s more of a biological disease so have to solve that ASAP.
And the final part is about children, don’t really see why he spend one third of the book to write about how to provide children with a good sleep , adding a bit of personal experience would be better, like describe real life situations where the author or his family members once have trouble sleeping and how they eventually solve that.
