I've been there before. The day before a paper is due, I've stayed up all night working on it. I've also done this in the work world (at my former company, not at PCCC). Let's face it. Staying up overnight stinks. But, if you have to, it's good to know the answer to this question:

Note that this isn't to suggest that you SHOULD stay up all night working on something, but if the situation calls for it, it has some tips to keep you effective and focused.
I found this Web site through one of my favorite blogs, The Simple Dollar.
