I think it definitely varies for each person. If I let myself sleep until I wake up 'naturally' - it's usually 9-10 hours. I'd love to be able to get somewhere in the 6-8 hour range.

I drink a copious amount of caffeine to keep going during the day, too. (5+ cups of coffee and sometimes an energy drink, too)

That may mean sleep deprivation. If you have sleep deprivation, you will sleep longer for some days.

Afaik, 6 hours a day is not enough for optimal performance for most people. It is minimum where people can function with somewhat, but also one where your cognitive capabilities are affected measurably.
