For me dxm is the perfect psychedelic, the visuals during sigma blow anything else out of the water, they don't completely overwhelm your visual field, but they can persist for many hours in broad daylight. I've seen certain beings or entities that linger for the entirety of the trip, it's really amazing. This was after 1800mg, I had a massive tolerance to 2f (multiple 500mg lines in a few hours) at the time, I don't recommend doing this, but that was the best experience i've ever had even though I broke my ribs trying to walk down the stairs like a dumbass. I used some offbrand gels, and apparently they have a bit of a different formulation, they were obviously made to abuse. I saw a god damn muppet concert in my bathroom.
I want anxiety destruction, chaos and alien feelings, ambient sounds turning into full blown songs, closed eye visuals that I can control completely (like being a character in a movie), persistent visuals, the visuals are heavily influenced by music whether it's actual music or auditory hallucination music, doesn't raise heart rate, no stimulation, opiate like effects. So basically sigma plateau dxm, but without the weird physical side effects. I don't know that anything exists like that. Even ketamine is way different. DXM acts on so many receptors, I don't know that anything else could be like it.
Dxm is great and all, but after going through a mountain of K and 2F and several years worth of daily dxm, I think my bladder is a bit tired and my memory is pretty bad. It would be nice if they could develop something similar to dxm, but without the strain on the bladder. I developed the "permanent" tolerance to dxm ages ago, and after 10-15 years I tried it again, and it was the hardest I ever tripped. Just save it for once every couple years.
tldr what do i want? Everything.
