Actor and singer Lily Allen has been sober for almost five years, after having a publicised struggle with drug and alcohol abuse. Speaking to Glamour magazine last year, she credits going teetotal for getting her personal and professional life in order. "Sobriety has just changed my life immeasurably. I don't think I'd be married to my husband. I don't think that my kids would be thriving in the way that they are. I don't think that I'd have gone into finding acting and how much I enjoy that. I definitely wouldn't be getting as much sleep," she said. "I go to the gym four times a week. Pretty much every aspect of my life has changed as a result of my sobriety. I actually don't even know if I'd be alive if I'm honest if I hadn't got sober. So yeah, that's definitely at the top of my gratitude list when I go to bed every night is my sobriety."
