Idk guys I love the benzo+psych combo, I don't trip without them anymore. I have medical reasons to stay on low doses of benzos but I still push the dose on psychs and still trip. Now opioids+benzos+psychs... pleasurable but the trip does indeed become very muted. Better for the pure hedonist/escapist trip.
I don't think I'll ever trip again without preloading benzos to be quite frank, but also I don't think I'll ever go without benzos a day ever again unless my medical issues with my gut somehow resolve themselves at some point. Perhaps my long term tolerance allows the psychs to still break through; for instance, last night I took 15mg psilacetin (first trip in many weeks) on top of some o-dsmt and a few large doses of etizolam (14mg over the day total) and I still had a strong period of visuals, looping thoughts, 'the fear', etc. Very much blunted but at the time that's what I wanted, I've been stressed lately and needed some comforting.
YMMV but I don't believe in the 'benzos kill trips' mantra. 10mg diazepam saved my mind on a 750ug AL-LAD trip once but the visuals didn't stop, it just kept me from pacing in circles and broke my thought looping, allowing me to lay down and just breathe finally.
