yo, unless your on some CNS (adderall/meth, that stuff), you WILL NOT make it through an entire day without passing out. I regularly stay up until 2 am, sometimes until 7 am then fall stufffaced asleep until 12. Really, unless you are like me, with insomnia/ADD, and your used to low amounts of sleep, don't do it. I've done it a lot, and it's something to say the least when you pass out stufffaced in your last period of the day.
