Dude, if this stuff came in corked clay jugs with XXX written on the side, I would have to get it for that alone. But yea, it's the big jug. Only equivalent to 12.5oz of coffee (i.e. a "small") though, in terms of caffeine. But that could explain why I'm bloody exhausted, caffeine tends to make me tired. Well, except that being sick makes me bloody exhausted too.
