No I have that issue too, I'm not suprised considering the fact that invega apparently shrinks certain portions of the brain, not sure if it's reversible though. That and the fact that I literally couldn't sleep for nearly 4 months straight to the point where I suffered a ministroke because of it. I refuse to accept the fact that I sustained permanent brain damage but sadly I'm pretty confident that's what happened, all I can do now is try to live with it, accept it, and work around it. But yeah I have difficulty thinking throughly and clearly now.
