London, July 24 - Actress Katherine Heigl is desperate to quit her cigarette habit because she feels smoking has taken over her life.

The actress picked up the addiction six years ago, but claims it quickly got a hold on her and now influences every decision she makes, reported contactmusic.com.

'I started smoking when I was 24, because I'm an idiot. I don't enjoy it so much now, because I've become such a slave to it. I hate planning my life around when I'm getting a cigarette,' said the actress.
