Go read the can or bottle of the beverages you're drinking today. Here's a good example of the kind of thing some of you might find:
Carbonated water, caramel color, aspartame, phosphoric acid, potassium benzoate, natural flavors, citric acid, caffeine.
What do those ingredients do to your body? Are you draining yourself or fueling yourself?
Drink more water and start cutting out the sugary (or fake sugary) caffeine bombs. If you're relying on the bump from your drinks to get you through the day, you're masking a bigger problem and making your body pay the price.
