Okay, first post, so bear with me.
I weight out 100mg of Diphenidine into a gel cap and a 40mg booster for if needed later on. I had fasted for 24 hours before I tried this as I really felt that I needed to empty my system of a lot of shit.
After an hour or so, the 100mg didn't seem to be doing much at all, or so I thought. I decided to just swallow the 40mg cap and see what happened. Very slowly, things started to get a bit crazy,
Over the course of four hours, I more or less sat contemplating why I had done this to myself. Music had turned completely metallic and I was hearing very strange noises. A conversation I was having with someone over facebook was freaking me the fuck out because I didn't realise the other person was drunk - I thought I was literally going insane. I distinctly remember being too afraid to go to the bathroom, despite none of my flatmates being in.
What really seemed to happen was how I imagined being "dissociated"; I didn't feel like I was in the room or house that I lived in. My room seemed to be twice the size it was before and I spent most of the time curled up in my bed incoherently posting on the internet. I do remember feeling like a giant then a midget very instantaneously, which was very strange. I'm just hoping that there will be no negative side effects after this.
The last half hour was fucking awful. I felt that this was it - I had finally reached a point of mental retardation. Nothing made sense. Words just... didn't work. Everything on facebook seemed 'pre-generated', much like the post of a spambot or something. I had this sort of dread as I slowly realised that everything was in fact pretty coreherent, I just couldn't make much sense of it. I felt like a different person, as if I had been 'reset' or something, which was scary. This invoked quite an emotional response in me. I more or less just rid it out, as it reminded me of a typical psychedelic trip in which you think that it's never going to end.
Eventually, it ended with a complete pop. I was back in reality. I felt that I had visited multiple different realities, mainly of paranoia, but I came out of it feeling fully refreshed. It's so hard to explain, but there was no 'comedown' or anything; I simply just, returned to normal. I felt great. I felt like a snake who had shed its old skin, mainly due to getting out of my sweaty clothes and putting on my bed time gear, sitting down with some water and chatting with a few friends on IRC. No after effects whatsoever. I took some benzos to get to sleep after a while, watched a movie and just let it do its magic.
Anyway.,. I don't have many experiences with Ketamine or other Dissociatives but I would... sort of recommend this to others. I do feel like the experience as a whole was very positive, but at the time, part of it seemed like a scene from Trainspotting. I probably seem like an idiot right now, but this was my thoughts on this.
'Nuff said, I feel good now. Real good. I'm glad I tried it.
Apologize if this isn't the best format of a 'trip report' per se, but its a good description on how it made me feel.
Thanks for listening.
