People who combine energy drinks with their alcohol may feel more sober than they truly are, a new study suggests.
In experiments with young male volunteers, Brazilian researchers found that the men were no less impaired when they drank a mix of alcohol and the energy drink Red Bull than when they downed a standard mixed drink.
Drinkers did, however, seem to think they were less drunk reporting less fatigue, fewer headache symptoms and better coordination.
