Me nether, and I've done all the other things. This one just sounds too brutal and sickening.
However, I recently read the one from a couple of years ago about therapists' experiments with LSD for anxiety and other mental-health issues, especially fear of death for people with terminal diseases. That one I would try, terminally diseased or otherwise. As far as I know, it's not available around here.
Apparently the researchers have had amazing results. Guided by therapists throughout, people take what sound like fairly high doses of psychedelics and emerge with transformed outlooks about life, feeling like they've confronted huge universal truths. They feel better about death or whatever their issue was. The success rates are really high, so to speak. Later, even much later, many rank it among their most profound life experiences. A psychologist is quoted saying something like, with what other drug would you see that kind of results and not immediately rush to get it approved?
My own assumption is that it triggers something in your brain rather than actually taking you to see the universe's secrets or whatever. But if it works, it works.
