"I feel like I'm so good at raising a kid when I'm not working. I don't forget anything. I've got everything covered. It’s a real luxury to have a moment when I'm not scrambling... so that leaves me feeling pretty exhausted. I'm the person who falls asleep all the time. You invite me over for dinner or to a party, and there's a whole scrapbook of pictures of me napping. I've even been given a nickname because of my snoring." Brokeback Mountain star Michelle Williams struggles to stay awake as she balances her career with motherhood.
