Sake won't help you stay awake, though! We usually have several bottles of it at home, as we're determined to try as many varieties as possible. Some of it is really good, but it makes me so sleepy! lol
It might, by the soul virtue of its face-puckering foulness of the bitter and dreadful taste. In my experience, the only people that really drink it are some of the older generation Japanese and the young, stupid weaboos, most of whom don't even enjoy it but do so simply because other people will see them partaking of something that is Japanese.
I don't really play with energy drinks, anymore. I'll take some NoDoz if I have to, but they never are very easy on the stomach. [Insert number here] Energy, (you know the ones; the bad-tasting ones in the little bottles) are really the only way to go. That said, NoDoz are cheaper.
