Darrell Hammond opens up about his drug and alcohol addictions in his new memoir "God, If You're Not Up There, I'm F*cked."

"I kept a pint of Remy in my desk at work," the comedian writes, according to the New York Post. "The drinking calmed my nerves and quieted the disturbing images that sprang into my head ... when drinking didn't work, I cut myself."

Hammond, 56, spent 14 seasons on Saturday Night Live. He says he began using cocaine in 2002 and had to be "creative" with his use so his colleagues wouldn't find out about it. He later went to rehab, but relapsed in 2009. "I had the brilliant idea I should try crack," he says. Hammond eventually ended his addiction after months of treatment.

Although Hammond also writes about his fellow SNL stars in the book, he has no fear of their reaction to it. "I don't have anything bad to say about anyone there," he told the Post. "They all really went above and beyond the call for me."

"God, If You're Not Up There, I'm F*cked" will be released by HarperCollins on Nov. 8.
