If you need energy, eat good food. If you need caffeine, there are many ways of getting that. But to me the hot cup of coffee provides psychological comfort as much as it provides physical energy. Caffeine does not provide actual energy, like calories, and may degrade mental performance in the long run if you do not get calories and water.

I have never been a fan of energy drinks any way, so I admit my prejudice against them. You just can't beat a hot cup of coffee (or tea or hot chocolate) on a cold morning to get your day started. I use the hot chocolate on my scouts as they roll out of their sleeping bags on a cold winter morning. When it is cold, you can't get them to move. After the hot chocolate, you can't get them to stop!
