Singer Michael Ball was seen doing it on a daytime TV chat show. He learnt it from the late singer, Stephen Gately, who used it to calm his own performance nerves. Lily Allen's weight loss was attributed to its efficacy. American PGA players have been spotted doing it around the golf course. And Norwegian pole-vaulter Rens Blom credited his unexpected 2005 World Championship Gold to its powers. The internet reveals millions of anecdotal accounts of its success on phobias, addictions and anxiety. So nearing the end of my own two-year psychotherapy training, I wanted to discover what this mysterious "tapping" business is all about.
So I signed up for a day course at the EFT (Emotional Freedom Techniques) Academy in London's Regent's College, with Richard Mark, an advanced EFT practitioner and certified trainer, who has worked as a psychotherapist and hypnotherapist for 12 years. My fellow students are a mixed bunch of mental health professionals, lawyers, physiotherapists, trainee counsellors and full-time parents. Unafraid to challenge, the students are surprisingly curious and sceptical rather than gullibile. There isn't a sandal or kaftan among them.
