Vastness have you tried ephenidine? If so, how would you compare them? My one trial with ephenidine, I didn't really care for it. I have a lot more though, might need a higher dose. Just wondering how you would compare them, if you can compare them.
I have indeed used ephenidine, more times than the others, but diphenidine makes it all 3 of the well known phenidines (or diarylethylamines, I believe) that I have tried, the other one being methoxphenidine.
Ephenidine I found to be quite enjoyable, but not really something that I could truly appreciate before going into huge doses (200-400mg+, I think 500 or 600mg even was the max), much higher than what I usually see reported. But the extremely long come up, dragged out aftereffects, and general inconvenience of this was not really worth the peak of the "high". The ephenidine come up, before any perceptual alterations became apparent, was often quite enjoyable, like a gradual quieting of the mind, while the peak effects became more classically dissociative, and even familiar environments start to look less familiar. Even at this point however, the feeling of unfamiliarity and blank, quiet headspace was as far as it got, compared to the more sedating arm of the arylcyclohexylamine familiar where the outside world ("outside" being outside our minds, I mean) can start to look not just unfamiliar, but truly different. These properties of inducing a certain blankness in the mind as well as a feeling of gradual unfamiliarity versus a true difference I believe are shared by all the phenidines, to a greater or lesser degree, and perhaps all dissociatives - but arylcyclohexylamines exceed phenidines in intensity when it comes to the magnitude of perceptual alterations, and I believe phenidines exceed the capacity of arylcyclohexylamines to induce a blankness or quietude of mind - or at least, in the latter class the effect on the perceived "inner world" is far more variable, ranging from the truly psychedelic like ketamine to selective silencing of certain aspects of mind in the more functional ones, to some combination thereof.
Diphenidine, to me, felt something like the comeup of ephenidine, I remember thinking at one point, "this is like induced meditation", in the sense that I was truly in the moment, not thinking about the past, the future, the usually endless loops and trains of thought that run around in our heads incessantly were quieted. I had an complete feeling of acceptance about the world and my place in it. I have experienced this on ephenidine too, but usually at dosage levels that perceptual changes had also started to take place, and that even internally I was already altered enough that it was hard to truly appreciate this. With diphenidine, this feeling came earlier, and I was still very much
in the world, able to interact with it quite normally, and really appreciate the sense of
relief and peace that this mental quietness brought.
This was with an oral dose of 75mg. A few hours later, I decided to redose with about the same - maybe a bit higher, ~85mg IIRC - and at this point things got stranger, my body began to slow, and it became harder to think clearly, harder to actually overcome the silence of mind which was now like a suppressive force on the natural flow of thought and cognition, if that makes sense. I gave up trying to work at that point which I had been doing before and tried to watch a TV show but have absolutely no clue what happened in it. I would occasionally just find myself sitting doing nothing, having tried to change tasks and just suddenly got stuck, the mental processes that were regulating my actions too weakened to persist through the action. After a while I started to just get tired of the "weirdness", when I was starting to come back but was not quite back yet. Fortunately the onset of action and duration of effects is far more convenient with diphenidine that ephenidine, with an onset around 30 minutes and a full duration of probably 4-6 hours with moderate doses, again, IIRC.
I remember previously I insufflated 100mg and that experience I remember almost nothing of. I expect that diphenidine maybe capable of inducing the same type of perceptual alterations as ephenidine in a high enough dose, but I think at this point the induced quietude of mind would be so severe that it would be impossible to appreciate or perhaps even properly remember these effects. So there seems to be a very steep dose response curves, a 75mg dose I found very enjoyable and quite functional - although maybe more experimentation is needed with this - but 150mg even in divided doses a few hours apart was starting to become less so.
