I'm a bit more clear headed now (running on zero hours of sleep and in what would normally be the afterglow, but sort of rested) and can put words to the wrongness. It seems that all other effects were normal, but no matter how much I took there was absolutely no ego dissolution whatsoever. It's freaking me the fuck out, I mean that's what dissociatives do isn't it?
I'm hoping this was a one time thing, I mean, I'm taking a break from the NMDA drugs for a while (at least a couple weeks, but ideally months, don't know how long I can wait) then I'll see if this happens again. I dunno, it's like the one inviolable thing in my reality has been messed with, take dissociative -> go to my perfect world. But then it didn't happen. It's like 2+2=Giraffe or something. I had a panic attack while showering earlier. I'm sure I'll calm down after I get a good night's sleep, but until then...I might as well be Icarus drowned in the ocean after flying at the sun with my waxen wings, or Adam expelled from the Garden of Eden. Well it's not all horrible last time (last time dissociation worked properly, that is) I was able to take back a key realization with me. It didn't make life permanently great or anything, but it's a part of the puzzle to finding my own happiness and certainty.
Excuse me, I'm off to help someone unload a cannon from a van and then go watch a cheesy 80s action movie with some people.
