Yikes. I drink red bull "quite a bit", which for me means like maybe 3 or 4 a month. Usually it's because I'm going out at night for some reason and I'm not 25 anymore - so I need a boost to go to dinner or a show or whatever. But I'm drinking the 8.4 oz OG ones. Once in a blue moon I'll get a 12 ouncer but that's usually because I'm dragging hard.
