i don't take much caffeine. i only drink soda maybe a couple of times a week, and it's usually something caffeine-free, like sprite/7up/sierra mist. once in a while, i'll have a coke/cherry coke. i've all but shaken my coffee addiction, since it was hurting my stomach. too acidic, i guess. i do like tea, especially iced tea, so i'd say that's where the bulk of my caffeine intake comes from.
