Who gets the last word in?

hello. I plan to stay awake all night....even though i gotta work at 8! one of my store managers told me that sleep is overrated and that I should try just not sleeping tonight.... hopefully a lot of red bull and coffee will help. im trying this becaus the worst thing about working in the morning is that terrible feeling when you get up. He said just don't sleep at all. course this is not an every night thing.... just an experiment.
