It probably depends on each person’s situation. When I read it, I was very worried about sleep. I had a very elaborate ritual to help me to fall asleep, which did not work that well. I think reading the book helped to me to adapt a more accepting attitude to insomnia. Now I actually do not think about insomnia much, but only follows some common sleep hygiene measures, like avoiding screen, sleeping on time and getting up on time, etc. It works reasonably well.
I tried that book and didn’t find it helpful. Last time I checked there wasn’t much evidence that the method he proposes works
