The staff checked her for viruses, alcohol and drugs. Nothing. Then the woman revealed a key part of her diet over the previous two weeks: 10 bottles of 5-Hour Energy per day.

Math time, lady: If the product indeed provides a five-hour boost, that two-week binge totaled 700 hours of “energy.” There are only 336 hours in two weeks. Must have been one hell of a deadline.

Doctors believe the woman overdosed on one ingredient: niacin — also called vitamin B3 — which can damage the liver when ingested in high amounts. She was successfully treated and discharged after her symptoms vanished.
