It is becoming more and more apparent just how differently people react to this substance. I think Shulgin was on to something with it cnverting into psilocin in the body, but people metabolize and convert it at different rates, leaving some people with fast intense and short trips and others with slower more drawn out trips. It seems to take 45 mins to hit me and anything less than 17 mg is less than stellar. My friend took 25 mg and reading about how it hits everyone so quickly an hour later decided to eyebal a bit less than half of another 25 mg capsule, so roughly 35 mg. He felt another reality superimposed over our own. There were these beings that were contemplating whether or not to "scrap the experiment" while at the same time tring to communicate with hin to help the survival of humanity. And somehow it was all tied into some galactic garage sale....
I can say for this that I felt on Ayahuasca that a vine of some sort that I induced (for some reason I thought mimosa hostilis at the time was a vine probably because of caapi, this is before I really knew what I was getting my self into) Anyway I thought this vine was evolved from an alien species of cthulu and that it had ripped out my soul. I remember waiting tentatively for my soul to be returned to me. I think at this point I was just ready to stop tripping because I kept tripping things that just didn't make any sense.
Another example being, the guy I watched on my girlfriend's laptop screen walking down a path in a beautiful meadow while I was explaining to her that what I had gotten myself into was serious business and that it was not about fun and games-- ayahuasca became known to me as something special and very dear because it provided a feeling of connectedness to the rest of the world and the resulting feelings were not really recreational; I felt as though I had trampled on somebody's beliefs and I felt like an ass.
On the other hand, the intense visuals, seeing my girlfriend's face take on a different texture than skin, the guy walking down the meadow before I said "tread carefully down this path" and also the full spectrum of colors that I saw in a single amber color monitor speaker LED were very very enjoyable :D
I have to say for 4-aco-dmt by comparison 20-25MG was definitely getting there, and I'm waffling as to whether or not my experience with ayahuasca was too intense or not. It was very special, I think to some degree 4-aco-dmt was *KINDA* like mushrooms, but the geometry of the visual hallucinations and thoughts and feelings were certainly much more like ayahuasca for me.
Another feeling that I had from the ayahuasca that was pretty intense and interesting was that my physical existence had become ambiguously designed compared to humanity; I was basically no longer human and I had recalled the alien species of vine, and it occured to me that it was growing inside of my brain.
Needless to say, I really wanna go there again and explore those thoughts a little more though the foul taste of ayahuasca was so unpleasant. I'm aware that these are two completely different substances, but I'm wondering.... perhaps maybe 4-aco-dmt with an MAOI such as syrian rue? Maybe its time to start a new thread....
This chem is always a quick ride for me. 3 hours and I'm almost always near baseline. I've been pretty bad with nitrous too. These days I won't buy more than two boxes at a time and I save them for when I'm going to trip. Definitely all about laying down though. Staring at the ceiling can be a religious experience.
