Ey! bro im 35 still a stuther , i have tried all, \-nootropics (currently experimenting with) \-Sertraline, antidepresents \-Ayahuasca , shrooms, bufo \-Psycological treatment \-Speech therapy My main advice is fix was is making you insecure, i was fat, now im fit, i get some success in life, keep working on yourself, Learn about what is stuttering (stuttering is just a bad habit/behavior pattern), is soooo hard to work on the problem directly , **defeat all your other insecurities , and never give up , and stutter will decrease drastically**
