Began drinking to cope with Harry Potter fame, quit at 20: Radcliffe

Actor Daniel Radcliffe said he started drinking alcohol to cope up with the fame he received with 'Harry Potter' series of films and to avoid the feeling that he was "being watched" by fans wherever he went. "The quickest way of forgetting that you're being watched was to get very drunk," he said. He added he's been sober since 2010.
