If I get literally no sleep in a night, I'll be very sickly and weak the next day, and once I finally do sleep, I'll stay asleep for at least sixteen hours, which is the reason why I need at least some sleep every single night. It doesn't really matter how much sleep I get, just so long that it's five hours or over.

I used to work with my dad on his delivery route when he was a bread man. I'd have to go to sleep at around five or six at night, in order to wake up at midnight, in order to get to Philadelphia by one in the morning. This went on nearly every single weekend for two years until he retired (thankfully.) If I couldn't get to sleep at five or six, I'd have to load myself up with caffeine all day in order for me to get out of my own way. I only did it on weekends, but my dad did it six days a week for thirty years. I have no idea how he did it. I would never have made it that long.
