Help me energy drink

Having a pretty good day. Got up at 8 to take Diana to school. At 10 Rob picked me up for groceries in america. Here it is 3:30 and i've been up ever since. The great news is i start work at 6;30 and go til 3 in the morning. Yeah I'm screwed. I wanna go nap but i'm afraid of not waking up on time. Kath is bringing me home an energy drink on my lunch break. That'll be at 10 so hopefully that will keep me going til 3am. Probably not though. Hope i dont fall asleep at my desk. They might frown on that.
