I actually prefer sugar to coffee when I need energy - so usually I'll just buy a box of cereal before a long night of working. Usually the sugar is enough to keep me awake, at least so long as I keep eating it every so often. Once in a while I'll throw some chocolate in the mix, but not so much that there's a very significant amount of caffeine. But as that's my only caffeination, and it's a pretty small amount and pretty rare, I voted none. I know enough people who've blown all their dining dollars on coffee to not want to become dependent on it.
