It actually became very weird, I was sleepy during 24-36 hours of no sleep then I liked the feeling. I even had some hallucinations on the 3rd day, so my friends forced me go to room and sleep. If they wouldnt I would have stayed awake whole 72 hours lol.
Did you drank and caffeine beverages to stay awake this long? because that shit makes you sad later when you overdrink it to stay awake.
