Former NRL star Matt Cooper has revealed he's been fighting a battle against an addiction to painkillers since retiring from St George Illawarra in 2011.
Cooper, who played 243 matches for the Dragons in addition to representing NSW and Australia, checked into a private hospital last month to beat a year-long struggle with Endone.
The 37-year-old told News Corp he feared he would die in his sleep and broke down sobbing while holding his daughter's hand as he came to grips with his problem.
"It was a cocktail of prescription meds, painkillers," said Cooper.
"I was like, 'I'm taking too many pills here.' There were times there I was like, 'I'm not going to wake up.'
