Snow Patrol frontman Gary Lightbody tries to steer clear of alcohol - because he hates the person he becomes when he drinks.
The CARS hitmaker, 30, believes he may soon quit booze altogether in a bid to stop him behaving "like a d**khead".
He says, "I've always got my finger on the self-destruct button. I started drinking at 25.
"I was being an a**ehole. I was swearing at people, smashing equipment and acting like a d**khead.
"I loathed myself. At my worst, I'd do maybe 30 pints of Guinness on a three-day bender."
