If I had no care for my teeth or belly, I would drink soda all day every day, and not even for the caffeine. Just because I love it so. Alas, I have a soda once or twice a weekend, and then often with a splash bourbon of vodka in it. I have no idea what it is like to be hopped up on caffeine. I am a bit of a slug in the morning, and up till my current job, have never worked in an occupation that required me to be alert throughout the day. I've thought about trying those 5-hour energy shots or whatever they are, but never think I need that much of a kick during the day.
