Now I want to see what it's like to not do it," Neil Young told the New York Times. "It's just a different perspective. The straighter I am, the more alert I am, the less I know myself and the harder it is to recognise myself. I need a little grounding in something, and I am looking for it everywhere.

He told Oprah Winfrey, "It was really a profound moment in so many ways. The way in which Nic handled that moment was just perfect. Everything was just designed, I believe, for that moment to fuse us together."
Eminem - "I knew I had to change my life. But addiction is a f---ing tricky thing. I think I relapsed within...three weeks? And within a month, it had ramped right back to where it was before. That's what really freaked me out. That's when I knew: Either get help, or I am going to die," said the Grammy-winning rapper, who detailed his struggles with addiction on his latest album, "Recovery," and in an interview with Rolling Stone that mentions methadone, Vicodine, ecstasy and marijuana. "As a father, I want to be here for things. I don't want to miss anything else."
Tim McGraw - "When I first started, I was really nervous. You could hear my voice quiver. So I started drinking a bit and that helped. A lot of entertainers have a few drinks before going onstage and don't overdo it. Me, it turned into a bigger habit. But I stopped that. I was getting older, and I was thinking about my kids," said McGraw, who also credits his wife, Faith Hill, for helping him on the road to recovery. "I think I'm more comfortable now. I can feel a real connection with the audience that maybe I was masking before."

Liam Gallagher - Liam Gallagher has decided to leave alcohol well alone after 20 years of "messing about". "I haven't had a drink since New Year's Eve. I'm having a bit of a break. I went 20 years drinking and messing about. It's rubbish.""At Knebworth (in 1996) I thought we were doing one night and we were doing two. I got that mashed on the first I woke up to a knock on the door and thought I was at home. I forgot all about it. But I had to go and do it again. That was heavy."
Keith Richards - The notorious 'Rolling Stones' Guitarist has recently given up all alcohol after fellow bandmate Ronnie Wood admitted that he was addicted.

Ozzy Osbourne - The infamous Black Sabbath rocker has abused drugs and alcohol for most of his life. Although clean and sober now, Osbourne has frequently commented on his former wild lifestyle, puzzled at how he has survived 40 years of abuse. The bat-eater was actually fired from Black Sabbath in 1979 due to his drunken antics, and Osbourne spent the next three months locked in his hotel room taking vast amounts of drugs and alcohol all day, every day.

Iggy Pop - The wild recklessness of this punk-rocker's youth is well documented, but these days Pop is drug-free, with a regular workout regime that centres on 40 minutes a day of qigong, a series of movement and breathing exercises akin to tai chi. "I do everything my mom used to tell me to do, I'm just 50 years too late," he says.

David Bowie - While Bowie was on his Diamond Dog tour, he lived on a diet of milk, hot peppers, and yes, cocaine. During the height of his drug addiction, videos and interviews show him sniffling almost constantly, and responding to the questions with answers that only David Bowie could understand. It has even been reported that during the height of his drug addiction that he weighed a meager 95 pounds, earning him the title 'Thin White Duke'.

This is probably the first album Ive made where I've been sober for fuck knows how long."
Prince - The 'artist' has produced ten platinum albums and thirty Top 40 singles during his career. He has not touched drugs or alcohol since he became a member of the Jehovah's Witnesses in 2001.
