Drinking vodka and Red Bull or Jägerbombs is a seriously bad idea – and not just because they make you feel like shit the next morning.

People who get drunk on energy drinks and spirits are more likely to be injured, because they keep you awake, a Canadian study shows.

Usually, getting drunk makes people tired and want to sleep, but in combination with highly-caffeinated drinks, revellers are more likely to stay up later.

Leading author Audra Roemer states that people normally drink alcohol, get tired and go home. Energy drinks mask the tiredness, so people may underestimate how intoxicated they are, end up staying out later, consume more alcohol, and engage in risky behaviour and more hazardous drinking practices.
