i have more caffeine pumping through my veins right now than i have had in the last year. i was shaking before. i've calmed down since then. this is exactly why i should never become one of those coffee fiends. i'm glad now that i don't need that cup of coffee every morning to get me going. i would be beyond hyper. and once i've developed a tolerance for it and tried to quit, my caffeine headaches would be infinitely worse than they are now...and i only drink one thing of pop a day. (that's soda for all you non-midwesterners.) the only thing is that coffee is free at work and pop is not. the benefits certainly need to be weighed. eric would probably say to just quit them both. hmm...pretty sure that won't happen in the near future. i don't know.
