This is one of my New Year's resolutions. I know it's gross, but I seriously must have at least 6-8 per day (down from 12+ per day....eww!). I've tried to quit, but I get such horrible headaches. I don't like coffee or tea, so diet coke is my caffeine. Mike keeps telling me I'll need to quit when we're TTC, so I should start now; it's just so damn hard.
