Mandy Moore has only been drunk four times.The 23-year-old star hates being intoxicated and rarely drinks because she is scared of saying something she will regret when she is sober.She said: "I've probably been drunk, maybe, four times in my entire life.Honestly. I guess I'm a bit of a lightweight."I have a better time enjoying one glass of wine and just being relaxed.It's a bit of a control thing - I don't like not being in control of my words. I like to go to bed at 10pm, or 10:30 pm, because I like to wake up at 7 am."Mandy has also vowed to never turn to drink or drugs, like so many of her contemporaries, if times get hard.Instead, the singer-and-actress would throw herself into songwriting to cope with her problems.She added: "Maybe for some people drink and drugs work for them, but I'm not a tortured artist. I wouldn't turn to some sort of substance to make me feel better, I'd turn to writing."
