I did a single 48 hour work pass for the old company once during the peak of the helliest hell week that ever was. I existed off of Cheetos and black coffee until I utterly collapsed at 4am .. probably closer to the 47 hour mark. I smelled like a rendered hog and looked like an extra from a war movie. All I did was crawl onto a pallet of new cardboard boxes and pass out for 6 hours. Noone disturbed me... noone could disturb me. I then got up and did 18 more hours and then went home, showered, and passed out for 11 hours. I then ate 2 large pizzas in one sitting and still ended up losing 5 pounds for the effort.
Snore is probably not the word for what I did.
