My craziest oral experiences have been with <1g MHRB. I cannot fathom what 7+ would do to me.
I'm also smashed on one glass of wine, always had to cut benadryl tabs in half, have a laundry list of antibiotics that give me rashes or make my throat close, slept 36 hours the last time I took some nyquil.
Something is probably atypical with my enzymes. My mom miscarried a lot before and after me. I came out strange in a few ways.
I have sensory processing issues too.
I had one friend I used to drink with who needed 200+ grams of Caapi to remotely feel anything. Dosing him always made me so nervous, considering my own sensitivity. He could also hold 20 beers and walk a straight line.
2-3g of Mimosa is probably a safer bet for a person's first time, provided they are seasoned with psychedelics. I don't ever give people huge doses on the first go because you just don't know how someone will metabolize it. A traditional cup of Aya is around 50mg of DMT, and Daime only serves theirs at half that.
But I do think there is an X factor to breakthrough experiences that is nonphysical, all of this aside. Setting, psychology, astrology... who knows.
Some things will come easy, some will be a test
