Hi. I suffered from stuttering problem for over 20 years. I tried numerous methods to get rid of it. Breathing exercises, visiting speech therapists, I bought two gadgets (first speech gadget worked wonderful but only when I wore it), yoga practices etc... Till I met really good neurologist. I am so thankful, no words can describe how it does FEEL to be able to communicate again. How GOOD it feels to be able to make phone calls again without fear!
