yes i skip out on sleep about twice a week. i work a job 9pm-5:30am and on my days off if i get home and go to sleep i slepe the day away and then at night when im up all my friends are out with there plans so i do nothing. to make up for that loss i stay up instead of going to sleep i drink 2 tons of coffee and amp energy drinks. moutnain dew helps and other drinks to keep me hyper.
