EoFF must be tired these days, because a lot of threads have to do with sleeping. So here is my spin on it:
What is the least amount of sleep you can get and still function normally without using any stimulants (coffee, energy drinks, meds, etc.)?
I can usually swing five hours a night without any assistance.
Though, if I want to stay up on a night where I don't have work the next day, that's when I will use a 5 Hour Energy drink. Oddly enough, I feel fine without one and just deal with being tired until it naturally goes away in the course of my day.
