Difficulty: Moderately Challenging
Step1
Soda is the best weapon during these times...
To prepare, eat and drink A LOT of caffeine, so you'll all be hyper. Soda is invaluable under these circumstances. Granted, it will burn out eventually, so you'll need to keep the caffeine coming. You can even try walking to Starbucks in your pajamas, but we guarantee nothing.
Step2
You mustn't go to sleep. You mustn't go to sleep. You mustn't.... zzzz
Now that it's midnight, keep talking, keep doing things. You NEED to keep each other entertained, because... well, sleeping is a way of curing boredom. Do anything, as long as it isn't illegal, dangerous, or ****ty. Even truth or dare and freezing your bras, the most classic and cliche sleepover activities of all time, can be lots of fun.
Step3
Boo ya! You did it! Celebrate!
Once it's about 4, 5, 6 in the morning, and you've accomplished your goal, you can go to sleep until maybe 8,9,10 or so. You did it! Now, reward yourself. Get at least a LITTLE beauty rest. And don't forget to celebrate!
