How healthy are you?

I'm sad to say, I do everything possible to err on the side of health. I have two children who bring back colds from school, and I can get run down because of my long hours on Holby City, so I take vitamin C and zinc, exercise, eat fruit and veg and drink lots of water.

What exercise do you take?

I'm addicted to exercise and would train seven days a week, if Richard Davidson, my trainer, would let me. I have my own little gym with a treadmill and weights. We do about an hour, often at 5.45am, before I go to the studio.

Do you worry about your weight?

Yes, I think about it a lot. Richard has changed the shape of my body completely. Now I watch what I eat. I don't completely deny myself; I eat carbs, and I even had some of my son's chocolate cake yesterday.

How do you relax?

My wind-down is reading my youngest son a bedtime story. Also when my eight-year-old Lennon is giving me love - that's heaven. And being with my partner [DJ Jeremy Healy].

Is sex important to you?

Yes, of course. It's a great part of my life, but I'm into monogamy.

How much sleep do you need?

I have to get up at half five, so generally 10 is a really late night for me.

How much do you drink?

I've never been a heavy drinker, but I changed my lifestyle drastically eight years ago and stopped drinking for seven years. Now I'm able to have a wee glass of champagne.

What is your attitude to drugs?

I think taking drugs is up to the individual, but you can't work on a job properly and party. I enjoyed a very hedonistic time in my twenties, and that's changed. My kids are my priority now.

Are you happy?

Very. I've got beautiful children and I'm grateful for my career. Right now my heart, spirit, is involved in Holby City. I adore working on a show that 4-5m people see each week. That sounds narcissistic, but it's frustrating putting your blood, sweat and tears into an indie movie that never gets seen.

How do you feel about plastic surgery?

If it means you can look like Sharon Osbourne, then why not? It's not part of my life right now. I just look after my skin. I would like to be pale and interesting, but I have to use a fake tan. I just make sure it doesn't look too orange.

Have you ever had therapy?

Yes, because I lost my mother when I was very young. Finding yourself is a really good thing. I wasn't brought up to love myself, and I tell my boys you've got to because no one else is going to. If you don't love yourself, you're chopped liver.

NHS or private?

Bupa. Although I just sold my Notting Hill house and am renting in West Hampstead, where there's a wonderful NHS doctor.

Any vices?

My one sin is Diet Coke. By 4pm my energy has gone, so I get my nanny to buy tiny airplane-sized cans. That's not a regular thing, but I don't want to come across as 'Saint Patsy'.
