Pereira told teens how he struggled with alcoholism

Alex Pereira, the UFC bantamweight champion, revealed how he struggled with alcoholism starting when he was 12 years old.

"From the age of 12 I started drinking alcohol. It was a difficult period. Every year the amount of alcohol grew. Finally the moment came when I decided to quit. Where my home was, I had no knowledge of medical help or a group of people like those in the United States. After four years of fighting alcoholism, I managed to beat it," BJ Penn quoted Pereira as saying.
