YES, I've had the same experience, albeit with a lesser spectrum of substances. Alcohol doesn't help, cannabis might even make it worse (and I hate how heavily it clouds my mind). Apart from those, I've only had experience with stimulant-kind of drugs. Methamphetamine doesn't affect my stutter at all, while MDMA eliminates it completely. I've been experimenting on myself a bit since I discovered this about a year ago, but I haven't explored it much since the going is slow (I've set myself a limit of 3 months between sessions and I mostly depend on the company of a few friends who have their own pacing). But so far it has been quite enlightening experience. Like when I was at this club, free from my stutter for the first time in my life, filled with this MDMA-induced euphoria and confidence and just having fun talking to my friends, when I notice this cute girl eyeing me. So without thinking I come over and realize I have nothing to say. So I just stand there for a long minute, opening and closing my mouth like a fish while my mind races to come up with anything. Then I just shake my head, shrug and walk away. I'm always torn between laughing or cringing at myself when I remember this, but it helped me realize a few things. Like how I've learned to live with my stutter by structuring my life in such a way that minimizes contact with strangers. It was weird to realize that this was the first time in my 26 years of life, that I've tried to talk to a random person. That I completely lack some social skills and can only talk to people when I've actually got something to say. My other experiences since then have been a bit disappointing (though I've always been able to scrape at least some value of of them). I've been either trying methamphetamine (which sucked), spent the whole time talking to a friend or haven't prepared properly in advance (like the last time I had to purchase something ad-hoc and the pills clearly had lots of shit mixed in). Going forward I've committed myself to always go with some clean MDMA at hand, find some nice place, spend a few hours just drinking and getting comfortable and only taking anything if I'm sure the setting is right and conductive for this kind of thing. I've been thinking a lot what it is about MDMA that causes this. Trying to dissect its effects (euphoria, empathogenic-like effects, how it fills you with energy in the "I can jump as the ceiling's high" kinda way) and cross-check with other stimulants, but it's way too hard/risky to obtain these and too much work to do at this pace. So I'm kinda curious about experiences of other people. Has anyone had MDMA affect them in this way and tried, say, mephedrone?
