Daniel Radcliffe has spoken out about the reasons why he stopped drinking.
The Harry Potter star said he drank in order to find happiness but realised that alcohol only made him feel worse.
He also had advice for young people feeling pressure to drink and go out and get "mashed".
Radcliffe is currently starring in the film The Woman In Black which is based on a best selling book and play.
The film about a lawyer haunted by a vengeful ghost, topped the UK box office and made £3.15m in the UK and Ireland on its debut weekend.
