I got rid of it in 2006/2007 when I was having some really awful facial tics. I think I was on a dose of Seroquel at the time. I quit taking the AP, and took huge daily doses of excellent quality vitamin E.
Unfortunately, I'm not sure if I could go off my AP now without suffering some bad symptoms. The only constant movement disorder I have now is tremors in my left hand. And every few days, eye symptoms.
