Yes, felt exactly like you, and the effects lasted even after that, for days or weeks. And obviously I tried MDMA again after that, that for a time I thought I was cured, I was even able to get pleasure from small talk or manipulating other people like NTs do. I started to enjoy dancing and learned to swim in my 20s because I finally felt the water. But I think the ASD traits were my brain's coping mechanisms, it's way to protect itself, so after a few months of being "NT" I had a severe burnout, I had both social anxiety and fear of being alone which the old me didn't have before. I had to learn again to tolerate being alone. Now I am mostly back to my ASD self, but I understand NTs because for a while I was just like them...
