It's the same with me man. I've had times in my life where I'm 99% fluent & nobody knows I stutter. Then I majority had times where I basically couldn't get a word out and I block and spit when I talk. It's horrible...its definitely hardwired in our brains from early trauma...I figure if nothing helps me I mind as well try stuff like DMT, Ayahuasca, Toad venom ect. While I still have some life left. I'm just afraid of having a bad trip that brings out my past traumas and worst fears. If it's a good trip that helps me then I'm all in. The meditation & hypnosis combined with psychedelics sound promising tho.
