'I thought I was indestructible...'
Robbie has managed to conquer his addictions but felt that he was "indestructible" at the time - even though there could have been disastrous consequences.
He told The Sun newspaper: "I didn’t know that was my fast-track to death. You feel like you’re indestructible, I didn’t feel I was going to die. It’s only subsequently I realise I was close."
