Look up lemontek. Drastically shortens the experience, makes it much more consistent and the lemon juice overwhelms the flavor of the mushrooms.
Alllll that text just to say "grind/soak the shrooms in lemon juice first and it will hit harder and last shorter".
Meanwhile using the lemon tek the experience is consistently around 4 hours in length.
For me, this is the ideal trip length. I'm very rarely looking to spend my entire day tripping.
