Agreed--anything that comes in a keg and isn't beer should be cut. (Ok, Ok, beer should too.... I just am usually unwilling to make that particular trade-off.) Try iced tea (we NCians have to specify "unsweet", or it comes with as much sugar as a Coke) with some splenda instead.
Speaking of NC, Lasereth---you and I live half an hour apart. Why haven't we met up yet? If you're not doing anything tonight, we're having a major New Years Eve throwdown tonight, you're welcome to join us. It won't be good for your diet, though...
