Robbie Williams has told how anti-depressants are helping to put his demons to bed.
The singer, 42, told Radio Times magazine that he had a "weird summer" when he could not relate to anyone apart from his wife, Ayda Field.
The chart-topper, who has previously battled addictions to drink, drugs and prescription medication, said of his demons: "They've been all right.
"But it happens to coincide with finding a different medication ... It's called Brintellix. I had a really weird summer. Just couldn't connect with anybody, apart from my wife.
"I didn't know how to talk to anybody, even people who are with me every day. I was isolated, in my head."
He told the magazine: "It was troublesome and sad. Then I tried this anti-depressant and things have changed. The demons are quiet."
Robbie, who has two children with Ayda, said he could never touch alcohol again.
Asked whether he could do any drugs safely, he laughed: "Yep!" but clarified: "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."
The star also questioned the small royalty cheques he receives from streaming sites.
"The music industry is obviously in rapid decline. I don't understand it but it looks like record companies are running for cover behind Spotify," he said.
"Streaming seems to be a big deal. There must be some sort of Cold War covert (dealings) going on, because you get something like 0.006 pence per play.
"I've probably had a Spotify royalty cheque, but it won't be very weighty. I'm not a streamed artist. But we redefine success. Number one is number one, and you can't argue with popularity. Well, you could, but you'd be wrong."
