I've never even tasted an energy drink, they smell awful. I've never had a taste for coffee either, nor has my wife. We keep some around with a French press for guests.
My only caffeine source is Coke Zero, but I learned years ago I'm better off limiting my consumption. 1-2 12 oz. cans a week is plenty, the rest of the time I drink water and the occasional Gatorade.
