Darren Day has revealed that he went through “cold turkey” from alcohol and drugs following his appearance on the first season of I’m a Celebrity…Get Me Out of Here!

During his appearance on “Good Morning Britain” on Monday, the actor and singer said he was “ashamed” of his behaviour during the reality show in 2002.

He also praised singer Robbie Williams for saving his life, recalling how he sent him to rehab in 2019.

Speaking at the launch of a new season of the ITV show, the 55-year-old recalled his experiences in the jungle, saying: “I’m going to be completely open with you this morning because my experience is that when I talk openly about my recovery and things like that, people send me messages on social media saying that it helps them to talk about it. And I do.”

“But I want to be honest with you. I’ve never said this publicly before, but I stopped doing it overnight.”

Presenter Richard Madeley asked: “From alcohol, drugs or both?” to which Day confirmed it was both, adding: “Cocaine – the devil’s powder. And the devil’s alcohol. I literally went cold turkey in front of the whole country.”

The actor admitted that he was “drunk” on the plane to Australia, but did not think about the fact that he would have to stay sober in the jungle.

Day added that he didn’t tell anyone about his experiences on the show at the time and that he “hasn’t told many people” in his life.

The stage and screen star later took part in Celebrity Big Brother in 2016, admitting he did so to “redeem” himself as he was “so ashamed” of his time on I’m a Celebrity.

“I deeply regretted it and carried it like a burden on my shoulders,” he said.

“I was just an idiot and I’m not surprised that people didn’t like me. So with Big Brother I wanted to have the opportunity to make people like you, but now the media and the public can form an opinion about me.”

After his two weeks in the Australian jungle, he said, he “immediately fell back into active addiction,” but later received support from his friend Williams.

Reflecting on how the singer helped him, he said: “I owe my life to my mate Robbie Williams because in 2019 I broke down to Rob and he sent me to rehab in South Africa where I was given six months to live…

“I was absolutely ecstatic. I explained it to Rob and he said, ‘Leave it all to me, mate,’ and without Rob, I would without a doubt not be on this planet.”

Day said he relapsed at the start of the first pandemic lockdown but has now been sober for three and a half years.

Williams recently spoke about his struggle with addiction and mental health issues in a four-part Netflix series called “Robbie Williams.”
