I would be interested in seeing a comparison between a reasonable amount of caffeine and a 15 minute nap. For years now (High School, College, now work + grad school) a power nap followed by continued work has been a mainstay in my fight against the need to sleep regularly. (Although lately I've been trying for better time management... because I like sleeping regularly, and I suspect all-nighters are bad for the health). I don't think caffeine has any benefit in terms of getting work done. It will make me 'feel' more alert, but it doesn't seem to improve my brain function at all. If I'm tired, my output is still just as bad as it was before the cup of coffee; I just will not fall asleep at the keyboard... (Akin to being a wide-awake drunk from mixing alcohol and caffeine). After the nap I might be able to pull off intelligent thought for a few more hours.
