DOSE:
300 mg oral DXM
  10 mg oral Amantadine
BODY WEIGHT: 165 lb
I'll start with a little personal history. I've taken DXM several times before and I definitely like it, although it feels kind of unhealthy so I limit it to a couple times a year. I've also taken a variety of 'street' drugs, mostly hallucinogenics and party drugs.

For DXM, I like to trip alone and listen to music. I've gone on 'adventures' while on DXM (gone for a walk, played in the snow, that kind of thing) but I've also just laid down, closed my eyes and listened to music and tripped out. I was prescribed amantadine for ADHD about a year ago, and I take 10mg on an as-needed basis.

(It doesn't seem to have any recreational potential, btw.) It is hard to find information about drug interactions, and in my experience it does not mix well, so I've always been careful to make sure the amantadine is out of my system before taking other drugs.

So one afternoon I decided to take some DXM. I had a bottle of 20 pills, 15mg each, for a total of 300mg. That is only enough for a pretty mild trip, so I thought I would try adding amantadine into the mix and see how it goes. Amantadine is also an NMDA receptor antagonist, so I figured it might potentiate the DXM. I decided to take my usual dose of 10mg along with the DXM. When I take DXM, I like to space out the dose; it seems to make the mental part of the trip deeper but more lucid, and it reduces the body load. I slowly took the pills over the course of an hour, and I took the amantadine about 1/2 hour after the last pill.

The trip starts out the same as a DXM trip, but quickly becomes more intense and more visual. I put on some music, close my eyes, and let my imagination take over. I am transported to all kinds of cool places, completely new worlds. Here is a snippet that I wrote down the next day 'I remember a couple of cool scenes from the beginning of the trip. First was this massive stone temple, bigger than anything I have ever seen, kind of StarWars-like in proportion. Inside it had a peaked roof that made me think it looked triangular from the outside. There was massive and beautiful stonework walls (angled at 45 degrees) and kind of a powerful tranquility about the place. Sunlight/moonlight slanted in illuminating dust motes swirling in the calm air. I also remember a couple cool jungle scenes, specifically a scene in a primitive village dancing on the dirt around a fire-pit/stone portal, with a massive bonfire or blue apparition in the center that was some kind of god.' Pretty cool, I am having fun.

Normally I feel that on DXM there is no emotion, I observe the world as some kind of cold insectile intelligence. With amantadine there was emotion and human feeling in the trip. At some point I decided to move into my living room because there is this really comfortable armchair I wanted to sit in while I tripped. (I wanted to be in an upright position instead of lying on my bed.) Despite the intensity of the trip, I had little trouble navigating my way to the living room, although opening my eyes and seeing the real world was kind of disconcerting for some reason. I sink into the chair and proceed to trip even more than before, although this time things turned kind of sinister. All my visions started to seem artificial and almost like a theatrical play. I become aware that there are people in my visions, but only glimpses of shadows, nothing warm and human. I feel like I am being observed and judged by an unseen dispassionate audience. The setting for these visions kind of reminded me of the movie Where the Wild Things Are, an artificial indoor environment that is sorta meant to take the place of reality.

I remember crawling along a carpeted arch that spanned through a tunnel, all inside a huge indoor room like an auditorium. It was VERY real; I could feel and smell the carpet, that plastic foam smell, and I could sense the sound absorbing material of the chamber, and feel the climate control circulating air. Kind of a theme throughout the night was moonlight. It started as real moonlight, but became this uncomfortable sphere or spotlight of cold blue light that tended to conceal more than it illuminated. After an hour or two in the armchair I started to feel really emotionally/mentally uncomfortable, all my visions where being marred by this artificial feel, and had developed a decidedly sinister tone. I couldn't seem to escape, or steer the visions in a better directions, or just relax and enjoy the sinister vibe. (When an acid trip gets sinister, I actually enjoy it, but this was different for some reason.)

I decide to move back to my bedroom and lie down. I spend some time with my eyes open, and without music, to try and regain myself and steer the trip back into something cool and enjoyable. My memory gets pretty hazy after this point, but I think the trip was pretty mellow from that point on and after a couple more hours I fell asleep.

I will probably not mix Amantadine and DXM again. The amantadine did potentiate the DXM quite a bit, I probably had 5 times the visuals of a normal DXM trip, but the emotional element combined with the sinister artificial vibe make me very wary of this combo. Maybe I'll try it again, but I will take a lower dose just to get a handle on it and really try to understand it.
