I'm certain, with work and dedication that I will feel the same way. Practicing the techniques every day and coming out of my shell and minimising the fear. There are support courses every 2 weeks and full courses 3 times a year. So I believe, the problem wouldn't lie in the technique - but the person themselves, with lack of work and discipline. Treating the technique as a war against our stutter and having a sporting mindset, will get anyone through the first few months.
