When your stutter got better or worse, were there any changes in your life - meds, environment, stress, etc? I've stuttered all my life, but nowadays I rarely stutter. 9 months ago, I posted here about my experiences with 5-htp. I originally took 5-htp mainly for depression, but I discovered that it significantly improved my stuttering (improvement of 75-99%). However, this won't work for everyone because there are many reasons why we stutter. There has been research done on stuttering that mention increased dopamine (or it's opposite: low serotonin), or excess glutamate (or its opposite: low GABA), or excess of other chemicals are primary drivers of stuttering. (Here's the research paper: [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8423914/](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8423914/) ) Fast forward to recent months: I newly discovered that I don't need 5-htp that much anymore. I noticed that I don't have much depression, panic, and/or anxiety anymore, even without taking 5-htp. This is weird for me because, in the past 19 years or so, symptoms would return after I stopped taking 5-htp for a few days. The interesting thing is that I also notice that my stuttering is dramatically reduced, even without taking 5-htp. I still may have some hesitation when saying certain trigger words or sounds, but it's like 10% of what it was before. I can't fully explain why I'm getting better. For me, I think my depression/anxiety is deeply related to my stuttering. Take a look at the research paper because it opened my eyes.
