I just went through an experience of ayahuasca analog and psilocybin mushrooms last weekend. Analog was full spectrum freebase harmalas via peganum harmala, and cold water extraction of mimosa hostilis. Dosage would have been approx 4 hr moderate intensity voyage.
Added approx 2g of dried cubes to the above. 2g of my current stock is enough to have confusion, closed eyed visuals, occasional waves of open eyed visuals over the course of 3-5 hrs or so.
I've used harmalas and mushrooms before to great effect, but this experience was a little different: Had more of a DMT feeling than a mushroom feeling to it. Total "white-out" chaos for approx 3-4 hrs, with come up/comedown of about 1 hr each way.
