Clinton long claimed to get by on five hours of sleep a night,
but he's been trying to extend that number after a heart attack he partly attributes to fatigue.
He also notes, "Every important mistake I've made in my life, I've made because I was too tired."
Monroe's insomnia, which she treated with sleeping pills, was reportedly tied to turbulent emotional spells.
The day before she overdosed, she became enraged on hearing that a friend had nabbed 15 hours of sleep.
Few writers have lived entirely free of insomnia, and it has struck not only those tormented,
'neurotic' artists for whom the inability to sleep might seem only one symptom of a more general emotional malaise.
Writers have used all available means to escape this malady.
The insomnia of Dickens and Whitman drove them out of doors for lengthy nocturnal walks.
The friend and biographer of the Bronte sisters, Elizabeth Gaskell,
reports that Charlotte and Emily walked in circles around the dining room table until they were tired enough to sleep.
For Ernest Miller Hemingway, not surprisingly, sleeplessness is analogous to a wild animal or a beautiful woman
something either to be conquered or endured with manly stoicism,
so that the insomniac's noble acceptance of suffering becomes a form of 'heroic' behavior.
