Wide Awake (2006)

Filmmaker Alan Berliner chronicles his lifelong battle with insomnia in this intimate documentary. The cameras roll as he tries to quiet his overly active mind so he can get a decent night's sleep, capturing the details of what it's like to suffer from a chronic sleep disorder. As he struggles to find balance, his friends and family -- who endure the worst of Berliner's bouts with insomnia -- question whether he really wants to find a cure.
