I feel like no one should have to be warned of this. I like to think that most of us have the common sense not to overdo it on the energy shots. But, alas, as you’ll see by the Amazon review below, there are idiots among us. It seems unfair to give the product a two star rating. The product seems to work just as it should. 5-hour Energy should give this person two stars on the intelligence scale that I just invented in my head. It’s out of 71 million. So, yeah. Two stars is really bad.
