I tried 2C-E a couple times a long time ago. I think it was a relatively low dose. It was really interesting how mentally I felt mostly sober. But the visuals were so intense I got motion sick. It started out with tracers as I waved my hand. The textured paint on the walls looked extra 3D and the walls started to breath. The swirly pattern on the bathroom linoleum looked like chocolate milk. My posters turned into cartoons. And when it was all overwhelming and the motion sickness really kicked in, I closed my eyes and was greeted by fractal machines that built the molecules of the world.
I don't recall any really profound thoughts, introspection, or feelings of intoxication. Which was a strange difference to me compared to things like 4-ACO-DMT and LSD, but I liked it.
