Well, I went for the 7.5mg dose.
Interesting.
A few comparisons with DOC (the only other DOX I've tried).
1. Come up time seems a bit longer. Looking at my trip notes, I was experiencing fairly intense visuals by the 2 hour mark on 4mg of DOC. On DOM I had first alerts at about 30 minutes (similar to DOC), but it took a long time to progress.
2. Stimulation. I didn't notice much more stimulation on DOM as compared to DOC during the come up. However, it was different during the Peak (more on that in a bit).
3. Mental effects. DOM seems to drag you I a bit deeper. It's easier to get lost in thought than on DOC.
4. Visuals. A marked difference between the two. On 4mg of DOC, objects would dissolve in psychedelic dust, and then shift around. As an example, I had a shirt hanging on the wall: almost as soon as I looked at it, the writing on the front would pixellate into a sort of neon yellow dust and float off to the right. It was impossible to stop this happening so at one point I was laying flat out almost drooling (sounds very flattering I know).
On DOM, once the visuals really kicked in, they were more like time lapse films (think of videos showing plants growing as an example), but I was fully aware of the frames changing. This would start with a sort of twitching in my left eye after which the right eye would join in and the next few minutes would be like uncontrollable blinking. Every blink changed the perception of what I was seeing. The shirt on the wall would change position, it would change shape, the writing would move etc. However, it was not smooth like DOC. I guess this is caused by the increased stimulation of DOM? In summary, DOM is IMHO every bit as visual as DOC, but in a different and again, IMHO, not such a good way.
The twitching visuals lasted for about 3 hours, becoming regular and lasting longer during the Peak (I'd say between about hour 6 and hour 9) before tapering off.
5. Bodyload. I’ve never encountered bodyload issues on any psychedelic drug. I find myself having to perform more bowel evacuations than usual, but it is not really an issue. I have never suffered from sickness. DOM and DOC are no exception to this. The only negative bodyload is some jitteriness during the come up phase. I went for a walk for the first two hours when I took DOM and I think this helped a lot. After the initial two hour period there were not any noticeable negative effects for me.
6. Duration. It has been said that DOC is longer lasting than DOM. I think that in terms of the peak effects, they are of similar duration; on both substances I’d say that the real peak has passed after twelve hours. The extra few hours on DOC is more of an afterglow effect where there is some residual stimulation which can either be enhanced by using another substance, or just enjoyed for what it is. DOM seems to taper more quickly. Having said that, I’ve been able to sleep after twelve hours on both substances.
In summary, I definitely prefer DOC to DOM; it seems a much smoother ride. Having said that, DOM (at these doses anyway – 4mg DOC v 7.5mg DOM) appears to have the ability to take you deeper. When on DOC I am able to just sit back and take the ride. In some of my notes I wrote after a particularly intense period of visuals that “things are just doing their own shit”. On DOM I found myself questioning what I was seeing a lot more; as Xorkoth says, DOM seems to have something of a delerient effect that isn’t there in other substances such as DOC). Anyway, I still have 7.5mg of DOM left to play with and I will take it when I have less tolerance as this test was performed just five days following my 4.5mg DOC trip.
