I'm highly concerned this person never ever posted again... This would be a shame if his trip was sour.... because psychedelics can alter your state of mind from one where you feel you must analyze everything you say, to one where you trust yourself enough to let your mouth move freely. I got a good bit of my stutter down in high school with mindfulness meditation, and functioned fine in most social scenarios except ones I still viewed as dreadfully serious. After about 6 years of that, I took LSD for the first time in a very safe space (crucial) and began hysterically laughing at the absurdity of my anxieties. I never even think about how bad my stutter used to be, and I haven't had any issues since. Psychedelics work extremely well for changing your perception of the world around you, though meditation and other such techniques will change that perception as well if you practice them often and seriously. Before I go, consider why you never stutter talking to animals or yourself. Start framing everyone in your social circle the same way those things are framed. Even if they seem intimidating, they're just another animal trying to figure out life. Nothing you will ever say is serious enough warrant such anxiety over communicating.
