Yeah, I have to say I have a bit of a caffeine problem. Usually one or two cups of coffee in the morning and 1-3 cans of a diet cola later.
I actually tried to cut out all caffeine a couple days ago and was stricken with some pretty rough headaches. I have some gruesome cavities right now so the headaches I couldn't deal with. Figure I'll kick the caffeine for a couple weeks after I get the teeth fixed.
