You need to quit reading up on stuff, Mr. L.
Maybe start by reducing your Google usage to half an hour at a set time each day? A therapist suggested that to me and it worked wonders - before that I was wasting four or five hours a day terrifying myself during bad phases.
I can't lie, though, the citalopram has helped immensely when it comes to reducing the urge in the first place. It damps down the horrendous sense of urgency you get with anxiety, which makes it easier not to do stupid stuff.
