Cooper spoke to News Corp about his abuse of the drug Endone, which he started taking last year due to a neck injury suffered while working with his father in-law.

Cooper said things got so bad, he thought he was going to go to sleep and not wake up.

“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.’

“I Googled how people die from this drug and they just stop breathing.

“That is when I realised I had to tell my wife.”

The 37-year-old recently underwent a month of intensive treatment for addiction at a Sydney hospital.
