Freshman year of college I used to crank out all nighters on the regular, and did some every now and then through the succeeding years. Finish that big essay or project, take an hour and a half nap, then show up to class to hand it in and just phone it in for the rest of the day.
The last time I pulled an all nighter was last May when I was packing up my stuff and flying to move across the country. It was a struggle to not fall asleep at 11:00 PM and I felt like death lol.
