Don't eat or drink ''energy '' food/drinks (monster, red bull ect) they will make you crash hard. Stick to certain fruits and other foods that help you stay awake by releasing energy slowly. Also drink water and avoid tea/coffee for obvious reasons.

Take it from a old MMO veteran who used to pull all nighters so he could be up PvPing with his american buddies.
Also take regular breaks and actually go outside if only for a minute or two, fresh air does wonders for you.
Failing that do what I do every opening day for desert bus, sleep in the day and get up a hour before it starts (1am my time)
Also any of these work to.
