Yesterday, I had five (5) cups of coffee and two Diet Cokes. I am on my third coffee today. But something isn’t right. I feel like there is a fog machine running in my head. Is my coffee broken?

Someone told me recently about this thing called sleep. It supposed to be like a reboot for humans - clears your mind, puts your memory back in order, helps you think faster. They say it has been around for a long while and is very well tested. I remain trepidacious though. From what I hear, it is very time consuming. That is billed as a feature, but it sounds like a bug to me.

Has anyone tried this? How does it work?
