Morning all!
Drinking espresso is a much better way of ingesting large amounts of caffeine than drinking energy drinks. It's a different sort of caffeine and doesn't have the huge sugar content that makes you feel horrid.

Top tip: make the coffee in an espresso machine (I usually use a moka pot), then load it with more coffee grounds, put the coffee you just made back where the water goes, brew it again, and repeat based on how long you need to stay up.

I find once you get past the fourth cycle you get coffee that will curdle the milk you put in it, and give you heart palpitations. Keeps you awake for about four days though.
