That's an extreme dose. Did you take that much on purpose? I've once snorted 70-100 mg, it was degraded and I thought it was barely active first, but I was in for quite a surprise. Even degraded stuff is still active. This massive dose resulted in a mental blackout that lasted for about an hour. Before the blackout I had so intense visuals I couldn't see anything but visuals. After the blackout it took hours to understand even basic things like who I am, where I am, what time is etc. It was extremely stupid of me to do it but I learned a lesson or two to say the least. But I never had any signs of any physical danger though.
My 80mg of the fumarate experience, I only properly realised what I'd done a while after consuming it, having weighed 0.08g on my tanita one hundredth gram scale, I somehow justified it in the moment as being 8mg which I 'subconciously' knew to be incorrect the whole time, having previously calculated it, it's a strange story

... but I decided I wanted to do this 0.08g, tipped it into a gel cap and dropped it. My decision to do it that day was made hastily I remember, having gone out to eat with the resolve to trip later on, I returned home and swallowed after weighing, accidents helping one appreciate risk, fortunately or unfortunately
(I since invested in an AW gemini pro-20 (mg scale) which I used for for subsequent experiences with DMT and 5-MeO-DMT.)
Others' doses of 4-AcO-DMT: I thereafter gave a 40mg oral dose to someone which was felt very strongly indeed, who liked and appreciated it; also 30mg for somebody else who absolutely loved it and to whom I also gave a 20mg hit of vaporized DMT two hours in which was incredibly good too apparently. (All three of us between 150 - 180 lbs weight).
My experience broke down the doors on quite a few levels by myopic and telescopic powers of memory and thought, enhancing a sense of humanity and appreciation of the naturalness of objects, surroundings, materials and lifeforms. It did feel noticeably synthetic in quality for a time at the peak of my enormous dose for a first-timer, and perhaps compared with other dimethyltryptamines, but I found the early part of the experience entirely natural feeling and pleasing as was the tail-end to a degree, falling off into infinity like mushrooms and leaving me a sense of profound awe. So this drug is perhaps preferable in the sub-40mg range. Perception of reality was increased on this drug, by increasing an understanding and appreciation of Reality...
