Are you healthy?

Mentally I'm better than I've been in a long time. I kind of rebooted myself.

Ever spent a night in hospital?

Never. I've been in the loony bin, but I've never broken anything apart from my mum's heart a few times.

Do you worry about your weight?

Not obsessively; less than I ever did. There could be less of me, but one advantage to being a bit plumper is I don't have lines on my face. If I was skinny I'd look like Keith Richards. I quite like it when boyfriends get a bit plump; they start to look a bit chunky and I think: 'Ooh, hello, you're a keeper.'

How much do you drink?

I follow an AA programme, so it's total abstinence. I've been doing that for about a year, and it's the best thing I ever did. When you're doing that stuff, it just becomes like Groundhog Day. I'm not more interesting when I'm wasted; I'm much nicer when I'm not.

And drugs?

Again, abstinence. Done the tour, worn the T-shirt, hate the band.

Attitude to smoking?

I never smoked until I was in my mid-twenties because I used to hate my parents smoking. I was always emptying the ashtrays and hoovering up. I stopped for eight years and then stupidly had a puff on a cigarette and started again, but I'm over it now so I'll wean myself off ...

Is sex important to you?

Very important - enjoyable sex. Gratuitous sex isn't. The key is vulnerability, intimacy and affection.

Have you ever had therapy?

I've had therapy for 16 years. I was raised in a typical family where you don't tell other people your problems, you discuss it with the family - but of course that never happens. I used to mock it. I'd say: 'Oh it's really American', but then I did it and it was great for me.

How do you feel about cosmetic surgery?

It's personal, and if you want it, then great. I have friends that are really extreme. Amanda Lepore had a sex change and turned herself into Jane Mansfield. She's an amazing invention - you have to be a bit of a warrior to have your whole body rebuilt.

Notable accidents

The joist of a massive 6ft-wide mirrorball fell on my head eight years ago during a sound check. If I'd been two inches over I probably wouldn't be here now. The guitarist, John, told me the first thing I said was: 'How's my hat?'
