I've just seen the news, and the Swedes are running an inquiry into three people who might have died from mixing red bull with booze. I like to think this is the case, and it's just the tip of the iceberg: not because I have anything against red bull, but because of the image of dozens (nay hundreds) of ravers and cyberfreaks dropping dead from badly mixed energy drink cocktails it conjures up.
Of course, it's more likely allergies or some damn thing, rather than synergistic poisoning."
