Jamie Kirchick reports from Belgrade:

How does Petrovic and his team ("me and my friends," as he describes them) claim to cure homosexuality? Quite simply: Patients must cut out junk food from their diet, "drink a lot of water," "reject anything that is diarrhetic, alcohol, caffeine," engage in "physical activity," "rest [at] appropriate times." Plus, one "must think about good things." Oh, and receive regular enemas.

There's an audio interview with the "doctor" as well.
