I'm reading some of the topics in here and I can't believe people drink vanilla coke. I don't really think caffeine is a bad thing. It is a natural constituent of teas and the coffee bean. Overdoing it is a problem. There is almost nothing natural about vanilla coke, and to think of how the Coca-Cola Corporation has people all over the world hooked on their gut-wrenching (literally, for the phosphorous in the beverage) product. I mean, who cares what straight edge really is. Just be smart and do the best thing.
