Well it is very kind of you to endorse what most people do or did. I see nothing new. I see what my mother used to say - and Ovaltine or Horlicks is a warm milky drink. Coffee was never a good idea. Most people have 90 minutes naps, which, incidentally, can make you feel more sleepy. The other suggestions are natural for most people too. And driving a car when you are sleepy is what happens to ANYONE at any time of the day - and you should pull over.
Not knocking the idea. But frankly, been there and done that.
