If you look at the persistent popularity of energy drinks, ephedrine, Adderall, and the like, you might conclude we're a nation of long-haul truckers, trance DJs, and meth cooks. Or you might conclude that Americans are just really, really tired.
Honestly, both are true. If you're tired all the time -- or if you're one of the aforementioned special-interest groups, in which case a life of sleep deprivation is almost a given -- read on for reasons why that may be. Hopefully, you'll end up with better sleep, and as a result, a life that sucks far less.
