Ever have one of those mornings where you literally have to drag yourself out of bed and the only way you think you can function the remainder of the day is with the help of an energy drink? Better yet, how many of you are regular energy drink consumers?

Consumer Reports magazine reported that even when an amount is listed on a label,  it's not a gurantee that it's accurate. Apparently 11 of the 27 top-selling energy drinks do not specify the amount of caffeine on the label of their drinks.
