I am not an ex-stutterer, I don't believe there is a cure. I still occasionally block on a word. I have been on National Health Service speech therapy twice, Hypnotherapy, and a 3 week (15 day) course at huge expense. The only thing I have found that gives me control of my speech almost always is an approach based upon costal breathing. There are lots of companies offering this Worldwide, in the UK we have a non-profit charity called [Empowering Voices](http://www.empoweringvoices.co.uk). Life changing stuff to talk without fear.
