Im starting the MPI Programme in May. As im based in the UK and there is only one therapist who does it so i have to wait. I actually received the throat microphone just now in the post. He had put me in contact with someone on the programme who said its the best one hes been on so far. Also he sent me videos of another client who was doing a 5min phone call and didn't stutter once. It is expensive but if i see no results within 9 months i get my money back on therapy costs. I also did the McGuire program but it wasn't for me. I would say i was fluent for 2months but didn't like the fact you don't sound as a normal speaker. I will be posting about my progress once i start the program
