Do you use any of those energy drinks that are on the market? There's "5 Hour Energy," "Monster," "Rockstar," or "Amp." A new government survey out this week found that the number of emergency room visits by people who'd consumed those drinks doubled from 2007 to 2011. Most of those visits involved teens or young adults. More than half of the patients had consumed only the energy drinks, while 42% had the energy drink mixed with alcohol or drugs like Adderall or Ritalin. The report says the energy drinks can cause rapid heartbeat, nervousness, seizures, insomnia and headaches.

The beverage industry insists the drinks are safe and say there's no proof linking them to health problems.
