I had a noticeable stutter through childhood up until about 14 or 15. something changed in me and I learned how to control it and be a covert stammered. then at 3rd year of uni, about 20 y/o, it came back after I realized I had to do a big presentation at the end of year. it made me remember inhad a stutter and I thought there is no way I can do the presentation. that lasted for about 3 years, and it got worse and worse until I found the Mcguire program that helped me.
