Chiming in mega late here, but the very reason you are having bad trips, is simply because you are trying to control it. Mushrooms are a wild ride and its very different every time. BUCKLE UP, and dont try to control anything (yes that means if it goes bad)
And i may be an enigma, but i literally HAVE to smoke weed on psyches. It helps me. When it gets a little weird, i smoke a bowl. I guess that depends on your relationship with weed.
