"I'm sure Gareth would have been doing this, and I hear he is also being taught the Maguire Programme, which trains you to change the way you breathe. These aids can help in the short term, which is why he appears to be speaking fluently when interviewed on TV. But, as we could see on Pop Idol, when he hits a word he may have wanted to avoid, nothing controls the stammer. At this point, all his mental energy will home in on getting that word out and, believe me, a bad stammering situation is mentally and physically exhausting. You end up with throbbing temples, an aching throat and tension throughout your body."
