Like being drunk
I used to do this a lot when I was in my early teens, and still do once in a while for the sake of studying.
The first day, you don’t feel it past your morning coffee. The next day, you feel WEAK. Near the end, you feel even weaker, you can’t think, you can’t walk straight, and you even have trouble speaking.
But yeah, it’s a blast. You don’t waste any time in bed.
