“All rehab can do is tell you what’s wrong with you and then suggest ways for you to get better.”

“I’m telling you, the ingenuity of alcoholics is something else. If only it could be put to some kind of good use. I mean, if you said to an alcoholic, ‘Look, the only way for you to get another drink is to cure cancer,’ the disease would be history in five seconds.”

“‘Ozzy, why do you drink so much? What’s the point?’The right answer to that question was: because I’m an alcoholic; because I have an addictive personality; because whatever I do, I do it addictively. But I didn’t know any of that back then.”

“It’s just human nature – isn’t it? – to be more attracted to something that’s taboo. If someone tells you not to smoke, you wanna smoke. If they say, ‘Don’t do drugs,’ you wanna do drugs. That’s why I’ve always thought that the best way to stop people taking drugs is to legalise the f**king things. It would take people about five seconds to realise that being an addict is a terribly unattractive and pathetic way to be, whereas at the moment it still has that kind of rebel cool vibe to it, y’know?”

“They teach you how to handle life in England, but they don’t teach you a thing about death. There’s no book telling you what to do when your mum or dad dies.”

“You never really know what’s going on inside Tony Iommi’s head. He’s the total opposite of me, in other words: no one’s ever in any doubt about what’s going on in the pile of old jelly inside my thick skull.”

“If you’re determined to commit suicide, you’ll blow your brains out or you’ll jump off a tall building. You’ll do something that you can’t take back, in other words. When you ‘try to kill yourself’ by taking too many pills – like I did – you know you’re probably gonna get found by someone. So all you’re doing is sending a message.”
