I’m 24 now and a year ago I took psychedelics with the intention of curing my stutter. I would say I’m a professional at this point because I took various amounts of psychedelics. Although, when I cured my stutter was I took a heroic dose. (Basically a lot lol) Not to go too much into my experience but it was life changing in the sense that psychedelics change your perception of reality. In terms of the stutter, psychedelics taken at a high enough dose will undoubtedly lesson the come up anxiety attached to your stutter. Which in turn will cure your stutter since people who stutter usually overthink their conversations. Psychedelics taken at a high enough dose will eliminate all social anxiety. For me, It took one 6-8 hour 6 gram mushroom trip to reset my brain. It’s been about a year since that experience and I have stopped stuttering completely. If you have any more questions I’d be glad to help!
