Coffee is not bad for you, as long as it is consumed in moderation. I have one cup a day, usually mid-morning, and experience no adverse symptoms. Granted, consuming any caffeine after 3-4PM can disrupt your sleep cycle (even if you easily fall asleep, it can cause you not to sleep well), but there is nothing harmful about 1-3 cups a day in the AM. There are several studies indicating coffee is even a preventative for a few diseases (diabetes and heart disease, among others), and it is a well-known fact coffee contains high levels of antioxidants.
