There's a reason why energy drinks taste like chemicals. It's because they're full of them! The high content of caffeine and sugar is a recipe for health problems, and it doesn't even taste very good. If the numerous stories of people overdosing on energy drinks hasn't put you off, maybe the fact that they cause liver damage will. Or the fact that they cause more damage to teeth than soda. There are really so many reasons not to drink them.
If you're looking for an energy boost, try a green tea instead. It doesn't provide the sugar hit that energy drinks do, but trust us, you'll get used to it. If tea isn't your style, try an espresso or black coffee from freshly ground beans (not instant). You won't want to overdose too much on these, either, but one is fine.
