For me, it's a big task just decompressing from a "normal" fun weekend convention where I've done nothing more than light drinking.
I imagine decompressing from something like Burning Man would be even more intense... even without psychedelics.
(I know psychedelics are obviously a thing at Burning Man, but I don't know if it's 25% or 50% or 75% or 99.99% of people using them...)
As a side note, I know somebody who permanently changed their gender identity after a mushroom trip revelation. I've always wondered how long they waited after the trip to "finalize" their decision.
(FWIW, that was years ago and it seems like it was indeed the right choice for them)
