Isn't there some American energy drink that's still more potent, even than Red Bull? I can't remember the name I was given (this is hearsay, and the beverage in question may be an urban legend of some sort), but supposedly it's blue, contains a frightening amount of caffiene, and has chillis in it, among other things.
I'm not sure anyone has a reason to be drinking these damn things anyway. Not unless they're an athelete, a dimwit in expensive sportswear who wants to be mistaken for an athlete, or an underaged disco bunny who can't score amphetamines.
As for the horned one's drinking problem, might I humbly suggest there is a potential story there? I can't see the bugger meekly acceding to the twelve step programme. Anyway, a wine glass matches his taste for formal evening wear, doesn't it?"
