Caffeine: Coffee contains caffeine, which tends to increase energy and have an alerting affect. The coffee does not need to be "black" in order to have these effects. Adding milk or other dairy products should change the effect of the caffeine. Consuming sugar can have an energizing affect. Adding sugar to coffee may enhance the effects of the caffeine.
