In order of preference (though all are highly preferred):

- Americanos (and also long blacks);
- other espresso-based drinks;
- any quality black coffee (read: not Tim Hortons), with a penchant for hazelnut-flavoured coffee (though not because of hazelnut creamers, since coffee creamers in general are disgusting);
- caffeinated teas (green/white over black though, even though black traditionally has more caffeine).

I've consumed one energy drink in my entire lifetime; it was expensive, disgusting, and seemed ineffective.
