EMINEM O.D. NIGHTMARE

RAPPER Eminem nearly died from a 2007 methadone overdose and reveals, “It took a long time for my brain to start working again.”

But the recovering addict, who got hooked on prescription pain pills and downers while shooting his 2002 biopic 8 Mile, says his brush with death scared him straight. The Lose Yourself Oscar winner, 50, swears he’s been sober since 2008 and claims music “saved his life” — but the hitmaker admits he used to find drugs “f**king delicious.”
