Robbie Williams still thinks about taking drugs.
The 'Party Like A Russian' singer has previously battled addiction, and though he is no longer tempted to drink alcohol, there are some narcotics that he still has to fight impulses to take.
He admitted: "I don't want to drink and I don't want to take coke, I'm really pleased I don't take coke but I do think about ecstasy."
The 42-year-old star - who has children Teddy, four, and Charlton, 23 months, with wife Ayda Field - still suffers from anxiety but is usually able to successfully keep his struggles hidden from the public.
He said: "There is only a two-minute window that people see into my life.
"Four or five if I'm on Graham Norton, making a video or on stage. That is the golden panto that is my life. You put yourself in the best light possible when you can for the short amount of time.
"It's the Facebook life.
"But I still suffer from anxiety. As I look out at the skyline, I'm sure that at every window someone is facing their own worry and panic about their own life."
And while recording his latest album, 'Heavy Entertainment Show', Robbie went to counselling because he suffered a crisis of confidence about having to promote himself and the record around the world.
He told The Sun newspaper: "I've been to therapy again this year. It's a big do putting an album out, speaking to people like yourself and going on TV shows and then doing it again, country after country.
"Even if I was the most sound person, it would be stressful. And I'm not the most sound person -- I am the opposite of that."
The 'Angels' hitmaker is proud of himself for feeling "brave" at the moment as he frequently battles his low self-esteem when he has to perform live.
He said: "My level of confidence has always been chronically low, but I've still managed to take myself to the places I've been in my career.
"I've done gigs in front of 70,000 people and felt like sh*t and thought that this is so overwhelming that I can't do it. So I've been f***ing brave and I give myself a pat on the back for that."
But as he's got older, Robbie has learned better how to cope with depression.
He said: "It's either low-level or high-level depression. So I try to take care of myself the best I can. If that means resting and taking myself away for a few hours then I will.
"Depression is a lifelong thing and I know I can still work and still pull it off, even though I'll be feeling low. So I'm as kind to myself as possible."
