Wow, even DOPr? That's nuts. That stuff lasted well over an entire day for me. I took 6.6mg (a large dose) at 10am, stayed up and tripping absolute balls that whole day and night, tripped through the next day, visuals didn't go away until 10pm the next day (36 hours) and I had to take 3mg of etizolam to sleep at 3am.
Psychedelics have changed for me, in terms of duration and sensitivity. When I was young, I always came down sooner than everyone else, and needed larger doses than everyone else. LSD in particular, I couldn't trip on it even when I took 3 times as much as my friends and they'd be rolling on the floor talking nonsense and talking about the walls melting. I also used to get really intense bodyload and difficult come-ups. But as I've gotten older, something has changed, and now I am really sensitive to them, get zero bodyload, ever, and they last a LOT longer. I can take a half a hit of LSD now at noon and have a hard time sleeping that night. DOC messes with my sleep for 2 nights usually, it's why I don't reach for it nearly as often anymore even though I love it.
