I need to stay awake. We are out of coffee, energy drinks and sugary things.. Help.

It’s finals week.
It’s 4:15 in the morning.
I have an exam in 2 hours.
I haven’t been able to study for this one until now. Don’t ask.

Problem is, I’m falling asleep. Fast.
How can I stay awake and focus?
Blah, blah, get off Fluther. Shush.

Edit: I don’t know if this even makes sense.. I haven’t slept since two nights ago. Finals suck.
