Trigger oriented, usually related to existential feelings of emptiness. Asking the question "does my existence have meaning" for a long time would spike my pulse to 150+ and cause me to freeze up. Took maybe 18 months to wear off fully. I can still psyche myself out if I try today.

Other triggers were anything that seemed too unlikely to be reality. Waking up with 11111 karma on Reddit, strangers winking at my like they could read my thoughts, things of that nature.

It honestly wasn't that bad to live with.

After my 4th trip I had really sharp HPPD. That burn in effect you get when you stare at something for a minute plus, that took about 0.5 seconds for me. And then it took about 60 seconds to wear off. For about 2 weeks I had a constant triple or quadrupole or more image burned into my eyes. Eventually I learned to cope by shifting my eyes every 0.5 seconds like a crazy person, but it did stop the after images from accumulating.

That went away after maybe 3 months, hasn't been a problem since.

My advice would be to space out trips 12 weeks or more to avoid hppd, and stay under 400ug to avoid PTSD and crazy delusions. And if you are inexperienced with LSD really you should start at a dose of 150ug or so.
