I need to pull an all-nighter, after several all-nighters. Advice?

I have spent the past three days with a total of probably 3 hours of "nap" sleep. I need to stay up and finish these research papers and study for finals. Coffee isn't working anymore. Caffeine-coated aspirin isn't working anymore. Vitamins and supplements isn't working anymore. Exercise isn't working anymore. Only serious answers please, and I don't want to hear anything like "get sleep" or "blow off your work". Thanks.
