I cannot overstate the degree to which it has been lifechanging, after years of trials of various other things. Honestly it was overwhelming - like a months-long mild psychedelic trip. I never want to go back. I am much, much less of an asshole now, and I say that advisedly. (note: lower assholery indicates nothing in absolute terms - I am probably still quite a bit of one. But less! and gratefully, joyfully so.)

Edit: And this is me trying to restrain myself so I don't look like someone starting a cult...
