Hi. My name is Viktor and I conquered my stutter. The first time I went to therapy was when I was really young. I don't even remember the experience very vividly. Much like you I didn't have any success. Second time was when I reached my lowest point in life because of stuttering. I was 16, very depressed. I was very passionate to improve myself. It was the start of the snowball effect that led me to "cure" my stutter. However, I do not attribute speech therapy as the reason. It was my work outside of the speech therapist's office that made all the difference. I tried a bunch of things! You can see this [post ](https://www.reddit.com/r/Stutter/comments/1iej02e/how_i_conquered_my_stutter_got_jacked_at_the_same/)for specifics. All in all, the speech exercises are the best thing to get out of therapy. Once you get their full list from them, in my opinion, you are paying for somebody to talk to. Self-therapy alone can get you most of the way there, but some speech therapy is important.
