Pearce has returned to Sydney after spending a month in rehab. He has been stripped of the captaincy of the Roosters and is awaiting further sanctions.
Pearce has denied being an alcoholic but admits he has a problem.
“Emotionally I’ve needed to grow up, I’m under no illusions about that,” he said.
“I’m not going to hide away from the fact that I love to have a beer. It’s been an ongoing part of my life since I was 18.
“But for me it hasn’t had positive effects at all. Drinking and partying has affected not only myself but my family and my club.”
In a lengthy interview with The Daily Telegraph, the NSW halfback said he as an addictive personality.
“I have always been obsessive. I have been a lot like that with footy. To be honest, I haven’t had balance in my life. I have come in and played footy since I was a kid. I have never had balance.
“It’s no secret I haven’t handled alcohol great over my career. One thing I have learnt — I am not denying I love having a good time, I always love to have a beer — but it can’t serve a place in my life for now or the near future.
“It is always going to be a challenge. Like I said, I am not an alcoholic. I hate saying that because of the label. I am a binge drinker. I haven’t learnt my lesson to this point. Alcohol has caused me a lot of embarrassment. It clearly doesn’t sit well with me.”
He also opened up about that Australia Day party.
“I had gone with a couple of people back to the house (where the incident occurred),” Pearce said.
“Once again, I was captain of the club and I should have really gone home. That’s been a bit of an issue of mine when I drink — I don’t know when to stop, which has got me in a bit of trouble.
“I was at that house for a while before (I was filmed). I am not a disrespectful person. I had been at the house before that for an hour or so. Everything was pretty friendly. My actions, the more intoxicated I got, we’re definitely disrespectful, and totally unacceptable.
“That’s got me in this position. I was pretty drunk by the time that happened. I remember most of it. My actions — it’s not me. It’s not something I am proud of what led me to doing something so stupid. I haven’t got an answer for why I did it.
“It was just immaturity and alcohol. I am disappointed (about being filmed secretly) but hopefully this could be the best thing that happened. If he didn’t do that, maybe I would be drinking still and the season would just get worse.”
