I used to be able to do this - take a double espresso, wait an hour, and sleep through the night. But as I've gone through my 40's, insomnia's been a problem.

Further, Pollan's interview suggested that even if I could sleep, caffeine was interfering with "deep wave sleep" - so I gave it a shot. I consider myself lucky that none of the headaches or [extra] irritability kicked in, so there's that.

sleep through the night is not the same as quality sleep. Just like after drinking alcohol many people can fall asleep, but it blocks REM(?) sleep.

So, while you might sleep all night. It's low quality sleep.
