To each his own as they say. To be clear though I too got my psychedelic needs met in the 70s and 80's. It is not so much about feeling a need to gain or learn more. It's more that I enjoy doing it every now and again. It all depends though on the quality of the experience. If I were to say have a bad trip several times in a row I guess the desire to repeat would disappear pretty quickly.No doubt you would have a memorable time but having gotten that checked off my bucket list in the mid 1970's, I'm more into having a good time and smiling, while being here now.
What I've found with psylocibin, is that I begin to have uncomfortable body nervous system sensations before I have any psychedelic effects beyond color enhancements. It starts with nervous legs, but I can feel that sensation all over at higher dosages.
At microdoses, or even half doses I don't have those sensations.
