I'll tell you what my experience is, basically I had a very strong stutter and I tried various speech therapy courses, they helped me but not much. When I discovered psychotropic drugs 5 years ago my life changed, I started taking them for depression and anxiety but they also helped me with stuttering. I started with escitalopram but it didn't do anything for me, then I was introduced to Xanax and it helped my stuttering a lot. Then I moved on to my winning therapy: duloxetine and olanzapine and Xanax as needed. I was like this for 5 years and every time I had to go out with a girl I took Xanax drops and everything was fine. It was great because I was finally able to do what I couldn't do before. However, at a certain point I was changed from olanzapine to abilify but I felt a worsening in mood (not stuttering) then I went back to olanzapine after months of abilify and my stuttering worsened drastically. I changed psychiatrist and he introduced me to the current therapy: Duloxetine 60 mg Olanzapine 2.5 mg Abilify 5 mg Xanax 20 drops in the evening I can tell you as soon as Abilify was reintroduced to me I immediately felt an improvement and then now months later I feel that my fluency has really improved a lot. Compared to years and years ago I think I have improved by 70%. I read that there have been studies on the effectiveness of abilify on stuttering and I saw on Reddit that many found it to be good. Unfortunately, Xanax alone can be addictive and addictive. This is what I felt and right now I'm not 100% fluid but I finally feel free to speak and I'm very happy thanks to the drugs. Mine is obviously not medical advice but I hope my story helps you with anything only here. I just advise you to persist and sooner or later you will find the drug that is right for you and that will help your stuttering a lot. Unfortunately, stuttering is not widely studied and it is not yet known whether it is a psychiatric problem or a motor problem. But I can tell you that Xanax and abilify have changed my life
