His long-running battles with drugs and depression have been well-documented.
But Robbie Williams has revealed his ‘demons are quiet’ since starting on new anti-depressant medication this year.
The singer, 42, said he had a ‘weird summer’ when he could not relate to anyone apart from his wife, US actress Ayda Field, 37.
He said of the mental demons that have dogged him for several years: ‘They’ve been all right. But it happens to coincide with finding a different medication. For real.
Brintellix is usually prescribed when other more common medications have failed.
It works by stopping the ‘feelgood’ chemical serotonin from being taken up by neurons in the brain, and so increases the amount of circulating serotonin available.
Former take That singer Williams, who has two children with his wife, has previously battled addictions to drinks, drugs and prescription medicine.
Asked whether he could do any drugs safely, he told the Radio Times: ‘Yep! I’m not searching to do anything. But I definitely can’t drink. I definitely can’t do coke. I can’t do ecstasy. And I don’t fancy heroin.
‘Or M-Cat (mephedrone) or ketamine or any of those things. But maybe there’s a once-a-year special voucher that I get for good behaviour.
‘But not for any of those things. I’ll leave it to your imagination.’
Williams recently became the most successful British solo act in chart history – after his latest album hit top spot.
The Heavy Entertainment Show was his 12th album to reach number one, pushing him past David Bowie.
The 42-year-old first hit fame with boyband Take That, which sold 10million albums in the 1990s, before he left the group after tensions with Gary Barlow.
The success of The Heavy Entertainment Show means that he now has the same number of chart-topping albums as Madonna. The only solo artist who has more albums is Elvis Presley, on 13.
