^Quitting any drug is about wanting to quit first. I usually need external forces to cause me to quit things, i.e. an upcoming drug test, or a reprimand from my fiance, etc.
I feel like I'll never recapture those early lessons though. It's a bit like they say about MDMA - the magic wears off. Don't get me wrong, every once in a while, psychedelics still kick my ass. And I arguably trip more now than I did in the early days. Yet I find myself not wanting to dose as high. Perhaps I choose to avoid lessons? I do not know.
All I know is that there are still questions I have from psychedelics. Are there answers? I really don't know.
