Gucci Mane's gentle post-prison demeanor took many by surprise and even fueled a conspiracy theory that a Gucci clone had been released and the real Guwop was still in prison.

As it turns out, Gucci got sober over the course of his 39-month prison stint. "I felt like I couldn’t make music sober, I couldn’t enjoy my money sober," he said in a New York Times feature published Wednesday morning. "Why would I wanna go to a club and couldn’t smoke or drink? I felt like sex wouldn’t be good sober. I associated everything with being high. In hindsight I see it for what it was: I was a drug addict. “I was naïve to the fact that I was numb."

"I can’t say I felt happy my last six, seven years in the music business," he continued. "I was just numb. You told me that I was doing good or told me I was doing bad, you hated me or loved me, either which way I greeted with nonchalance. It was sincere nonchalance — like, I really didn’t care."

Salute to Gucci for sobering up. Here are five rappers more rappers who have kicked their own drug and alcohol habits.
