    Energy drinks are giving some people more than a boost; they are giving some a trip to the ER too.

    In a recent four year span, the number of people heading to Emergency Rooms after downing energy drinks has doubled nationwide.

    A new government report doesn't pinpoint the symptoms, but says energy drinks can cause insomnia, headaches, a fast heartbeat and seizures.

    Dr. Roland Griffiths with Johns Hopkins University says one of the main ingredients is caffeine.

    (Griffiths) "Caffeine is the most widely used mood altering drug in the world."

    From 2007 to 2011, the number of ER visits involving energy drinks shot up from about 10,000 to more than 20,000.
