Take That stars Mark Owen and Robbie Williams have talked about the impact rehab treatment has had on their lives.
Thirty-eight-year-old Owen entered rehab in March after admitting he had a drink problem and had been unfaithful.
In an interview with the Radio Times, Owen says: "In rehab, I was able to look at my behaviour, at who I was and who I wasn't. I'd kind of become this person I didn't really recognise. How did that happen?"
In a new documentary about the group Owen's colleague, Jason Orange, says of him: "Before, if someone was suffering, there was no time to deal with it. You'd just keep grinding on for the sake of business and success. This time, we [the group] have to put each other first. So there was no pressure on Mark to come back. Just when he was ready."
Robbie Williams, who received rehab treatment for drink and drug addiction, says: "No-one's got the emotional tools to deal with being looked at by a million people. Live the dream? Live the nightmare.
"Without rehab I'd be dead, not to be drama queen-y."
