from PageSix...JOHN MAYER suffers anxiety attacks and keeps a supply of powerful drug Xanax with him at all times. Mayer blames the attacks on "crossed wires" in his brain, but they are quickly cured by the drug - one of the combination of pills that Heath Ledger overdosed on, reports PageSix.com.
He says, "There are these incidental kinds of loopholes in my brain, where the wires can cross for a second and the hard drive crashes. "You can create dark neighbourhoods in your mind as easily as you can create rural wonderlands."
