Platinum selling singer, Fergie in a revealing interview with Allure, talks about overcoming her addiction to crystal meth:

“I had chemically induced paranoid schizophrenia,” she says. “At one point I gave myself an ultimatum, because I was absolutely sure the FBI and a SWAT team were coming for me. I said, ‘OK, if you walk through that door and they’re not out there, then it’s the drugs.’”

After a couple years, Fergie realized her choice was sobriety or a mental institution. So she went through therapy, attended Narcotics Anonymous meetings, and got a grip. Good for you girl!
