Customer Review

Reviewed in the United States on April 20, 2019
I read this on the recommendation of Amanda Palmer as heard on a podcast. If you’ve never thought much about sleep, this should have a lot of new and useful information for you. If you’ve read shallowly but widely about sleep, you’ll have heard most of what this book has to say.
