My advice is to stay far far away from psychedelics. I took LSD a few months ago after hearing about what great insights it can enable, or the euphoria it lets you feel.
I ended up having a bad, panic-inducing trip which caused something in my brain to flip and start having panic attacks and dissociation. The dissociation/depersonalization faded after a couple weeks (although those weeks were hell) but the anxiety and general feeling of weirdness still affect me.
I don't really feel like I've ever gotten back to how I've been before I took the drug. As some other commenter on HN said, "it's like throwing a wrench in your neurological cogwheels." The rewards definitely don't outweigh the risks.
