Well, yeah. While coffee itself isn't bad for you, caffeine definitely can be. It's an addictive substance. You might not crave it like some other drugs, but you will definitely feel symptoms of withdrawal if you go without it. When I was younger and drank a lot of pop, I would get pounding headaches if I went without caffeine for more than half a day.The problem with coffee I found is that when I started using it to give me that extra boost for work I started to depend on it more and drink more. Now one cup a day isn't enough anymore. So in the long run it's not going ot be healthy. Same for Red Bulls which will make you crash later.
