+1 on steering clear of most energy drinks. 5 hour energy - wish I'd "invented" it - not because it's good stuff; just the profit/production ratio is likely huge.

Anyway, I'd go with coffee (Iced if it's hot outside) or green tea. Green tea and caffeine in moderation daily are possibly beneficial for your health (neuro, cardiac), aside from getting you going. There's also the staring-into-light trick: can't remember the specifics, but the military showed some short-term benefits in pilots. This again, is for situations such as your current; not daily, long-term.
