Last October Panorama revealed the dark and shocking side of Seroxat, one of the world's favourite anti-depressants.

The feedback to that film was unprecedented with thousands of people contacting the programme.

For many who take the drug it is a tremendous help but in e-mails and phone calls many Panorama viewers said they showed signs of violence, addiction, self-harm and suicide.

This second investigation into Seroxat, "Emails from the Edge" has been driven by the viewers' response.
