10 signs you are sleep deprived on your Sub-I

1. You spend a substantial portion of your day dreaming about how nice it will be to ease into some warm sheets at day's end and scheming how to get the maximum number of hours (start undressing in the elevator, eat dinner with right hand, brush teeth with left...).
2. You have thought about looking online for the possibility of injectable caffeine shots.
3. You have mastered the art of the 30 second power nap - standing up.
4. You have mastered the art of the 30 second power nap, standing up - with your eyes half open.
5. When walking into conference, you dawdle at the door, so there won't be any seats left - because if you sit, you will fall asleep.
6. You have pinched yourself to stay awake.
7. You know all the good places in the hospital to take a quick 15 minute nap (that couch on the dark end of the visitor's lounge, that abandoned stretcher on floor nine...).
8. You've been timing your coffees in order to keep blood levels of caffeine constant, with a gradual decline towards sleeping hours.
9. You've thought to yourself "If I don't sleep for 15 minutes NOW or at least have some caffeine, I will truly die. I will just konk out right here on the floor."
10. You would rather be hungry from 4am to 2pm so you can have that extra half hour of sleep.
