Yes at some point for me it became much too easy to negotiate with the experience with LSD as where mushrooms just kick my ass whatever I want. Also the trips kept pointing me back to my life as if they were saying: don't come back before you really integrate some real answers in your life and stop randomly asking around for more novelty and enlightenment.
But I was stubborn and afraid to actually make work of self-actualization and reintegration. Instead I kept withing to desintegrate again and again. It's pointless resetting a computer again and again. What is important is to integrate the experience and put everything into place, then engage in new life experiences for a while before diving into the meaning of it all again.
I used to think deep metaphysical meaning was out there and I just had to keep digging at it. While I leaned a lot, one of the most important things I learned is that such meaning can only really have meaning when integrated into a grounded every day life. The mystical is very little if it is not put into perspective. That may seem paradoxical but spiritual asceticism is a dead end IMO.
But more planely, yes LSD got too easy and too predictable. I don't have anywhere near the respect for it as I do have for mushrooms, mescaline or DMT, though of course high doses of LSD are transformative.
