The first couple paragraphs list (1) regular sleep schedule and feeling more rested, (2) "no zombie feel" first thing in the morning, and (3) less anxiety. And then it says "I still feel these benefits are true but I've also discovered a new one."
So what's the new one?
The rest of the article seems to discuss #2 again -- that the author can wake up and be productive without the kick-start of coffee.
Is there something I'm still missing in the rest of the article? (Yes, I've had my coffee today.)
