Autistic comrades who've used NMDA antagonists, what was your experience?

The reason I ask is because I'm autistic, but I wasn't diagnosed until I was 18 so I never received any kind of assistance growing up. And every time I've used an NMDA antagonist drug, I've experienced amazing relief from all of my sensory issues.

I've never tried Ketamine, but I have used DXM and Nitrous Oxide, both of which are also NMDA antagonists. It's like they partially sever the connection between the mind and the body. Nitrous Oxide isn't very useful for this because it only lasts a couple minutes before you need to redose, but even on lowish doses of DXM I feel totally unencumbered.

My sensory issues tend to take up a lot of cognitive load when I'm out in public and interacting with strangers, resulting in social anxiety. My whole life I've been too focused on the feeling of wanting to crawl out of my own skin too much to put any effort into being social, making friends, or having fun.

But on NMDA antagonists that all just goes away and I finally feel free and clear headed in a way I had never imagined possible. They literally just make me feel free to be me. Has anyone else here experienced something similar? Is there any existing research on this?

Rules

1.) ableist language=post or comment will probably get removed (enforced case by case, some comments will be removed and restored due to complex situations). repeated use of ableist language=banned from comm and possibly site depending on severity. properly tagged posts with CW can use them for the purposes of discussing them

2.) always assume good faith when dealing with a fellow nd comrade especially due to lack of social awareness being a common symptom of neurodivergence

2.5) right to disengage is rigidly enforced. violations will get you purged from the comm. see rule 3 for explanation on appeals

3.) no talking over nd comrades about things you haven't personally experienced as a neurotypical chapo, you will be purged. If you're ND it is absolutely fine to give your own perspective if it conflicts with another's, but do so with empathy and the intention to learn about each other, not prove who's experience is valid. Appeal process is like appealing in user union but you dm the nd comrade you talked over with your appeal (so make it a good one) and then dm the mods with screenshot proof that you resolved it. fake screenies will get you banned from the site, we will confirm with the comrade you dm'd.

3.5) everyone has their own lived experiences, and to invalidate them is to post cringe. comments will be removed on a case by case basis depending on determined level of awareness and faith

4.) Interest Policing will not be tolerated in any form. Support your comrades in their joy!
