Well, it could be bad for you...everything you take too much can be bad for you, no matter what it is. Well, cocoa can cause issues such as headcahes, has a lot of calories, can cause allergies due to a couple substances in cocoa, plus it can also cause issues such as acid reflux and others. I love cocoa but it gives me headaches that are so bad. If you have a sensitive stomach like I do You could also face some unpleasant side effects.
