I read this post by Phillip Chan and I think I just might try it. I've been living on caffeine for the past 6.5 years of pre-med & medical school, opting for an extra cup when perhaps what I needed was an extra hour of sleep. It culminated over the weekend when I started wondering if I should prepare for fatal arrhythmias given the four cups of coffee I am drinking every Sunday. So I'm going to try and give up coffee for a week and we will see how that goes. I'm already taking a break from Facebook - might as well throw coffee into the ring too.
