That sounds familiar to me.

Ketamine with psychotherapy has become mainstream and legal I think in a wider context, and there are different ways they do it - one is to give that heroic dose under supervision with a drip which can be a controlled administration.

Psychedelic therapy with mdma or mushrooms is only legal in very few places. Personally I find mdma is more promising for what you (we) experienced there. There's a sort of ancient wiring due to childhood threats. MDMA has been proven to help soldiers with PTSD, which I think is a big adjacent to this (the vigilance being the common facor)?
