Mandatory reference: the brilliant Matthew Walker: https://www.penguin.co.uk/books/295/295665/why-we-sleep/9780141983769.html https://www.penguin.co.uk/books/295/295665/why-we-sleep/9780... I'm halfway through the book, and it has already influenced my behavior. I began setting "to bed" alarm, just like I set "wake up" alarm. If you don't have the time (?) to read the book, then at least listen to Walker's presentation at "Talk at Google". (Not to mention, he's an outstanding public speaker, too.) He has a segment where he talks about how sleep hits the "save button" to preserve your memory (after learning) to "persistent storage in your brain", as it were. Walker's work is urgent and important.
