I used to be a caffeine junkie. Any lull in my day called for a cup of coffee (or three). I once felt actual rage at a friend's island house, far from a grocery store or coffee shop, because the only available caffeine was in the form of a full sugar soda, and I couldn't handle the sugar. I was near tears in a restaurant with my children when I realized the only diet soda they served was also caffeine free. And by "near tears," I mean that I wanted to kill someone. It is not an exaggeration to say that caffeine ruled my life, and I needed a break.
