Ask HN: Most accurate scientific book on human sleep?

I am someone who is suffering from sleep problems since many years. And I want to know more on this topic. I read, at few places online including HN, that the book "Why We Sleep" is not completely accurate. Can someone recommend an ever more accurate book? Or "Why We Sleep" is the most accurate, albeit flawed, book out there?

I am also open to any series of articles/podcast or any scientific author to follow over a long time to learn about human sleep. I understand that not everything may apply to me, but still, learning is a good thing.
