" I’ve said it’s hard. Here’s how hard: everybody I know who wades deep enough into memory’s waters drowns a little. Between chapters of Stop-Time, Frank Conroy stayed drunk for weeks. Two hours after Carolyn See finished her first draft of Dreaming, she collapsed with viral meningitis, which gave her double vision: “It was my brain’s way of saying, ‘You’ve been looking where you shouldn’t be looking.’” Martin Amis reported a suffocating enervation while working on Experience.

Jerry Stahl relapsed while writing about his heroin addiction in Permanent Midnight. "
