Oh yes, nitrous oxide for example lets me surface and approach traumatic events without over-whelming anxiety that blocks the memory out. I've done years of talk therapy without drugs and the problem is that it's hard to let go of my ego personality when I'm talking to another person and it also takes a long time to get a therapist up to speed about what is going on with me internally, because I don't often even know. I did MDMA therapy with an alternative/underground therapist in the 90's and didn't get much out of it because it felt like the experience conformed to her expectations. I didn't feel free to let my mind wander.

I'm not knocking dialog-type therapy or psychedelic therapy, but maybe I'm built different and as a computer programmer figured out how to use these drugs to debug myself.
