"I can't imagine what other people think cold turkey is like. It is fucking awful. On the scale of things, it's better than having your leg blown off in the trenches. It's better than starving to death. But you don't want to go there. The whole body just sort of turns itself inside out and rejects itself for three days. You know in three day it's going to calm down. It's going to be the longest three days you've spent in your life, and you wonder why you're doing this to yourself when you could be living a perfectly normal fucking rich rock star life. And there you are puking and climbing walls. Why do you do that to yourself? I don't know. I still don't know. Your skin crawling, your guts churning, you can't stop your limbs from jerking and moving about, and you're throwing up and shitting at the same time, and shit's coming out your nose and your eyes, and the first time that happens for real, that's when a reasonable man says, "I'm hooked." But even that doesn't stop a reasonable man from going back on it."
- Keith Richards, "Life"
