I have taken DOC twice and DOI five times. Compared to DOI, I find DOC to be much more favorable. My experiences with DOI have been great; but it can be a bit much in terms of duration. The visuals are wonderful and the mind is blissfully invigorated for the first twelve hours or so. After a while I get tired. Every DOI trip I have taken has lasted about 20 hours. There is absolutely zero chance for sleep before it is over unless I use some sort of sedative. I always get an early start on DOx's so the duration is fairly tolerable.
The first time I took DOC I took 3 mgs orally. The second time I took it I insuflated 1 mg and took 2 mg sublingually. The flavor is a salty, sweet chemical taste, not too bad.
The first time I took DOC I experienced moderate nausea followed by projectile vomiting. This lasted for about 15 minutes. This occured almost simultaneously along with a sudden awareness of brilliant colors inside of my head. It was hard to tell if my GI tract had a chance to absorb all of the DOC. Immediately after vomiting there was a sense of divine awareness that lasted throughout the trip. This feeling is difficult to describe and more than made up for that brief physical malaise. The trip lasted fifteen hours and was characterized by a wide spectrum of colors seen mostly in what I suppose I would call my mind's eye. Every thing that was happening was occuring inside of my head. My body felt great. There was no body load, only a wonderful feeling of exuberant contentedness. This is not the speedy, rolling feeling that DOI gives me. Very few visuals other that color for my first trip until I lay in bed to fall asleep, and they did not seem inhibit sleep. There were rich fantasy images. Any thought that flowed through my mind was projected into beautiful 3D.
My second trip was perfect. It took an hour and a half to come on. This time there were absolutely no physical rejection of the material. It came on clean and stayed clean throughout. This trip was much more visually intense, although not near as much as LSD. It is more colorful than DOI yet somehow less hallucinatory for me. With DOI I often feel like I need to take something extra, such as 2C-I or 2C-E, in order to achieve the proper head space. DOC is more of a total package. Nothing is really left to be desired. The only thing that I did not like about DOC is how it affected my taste buds. Eating food was a chore and was not appealing. This could have something to do with the nausea of the first trip, but that would not explain the presence of the effect on the second trip. While the anorexia experienced on the DOC was undesirable, I found this chemical to be preferrable to DOI. (I don't recall DOI supressing appetite) I will definitely be exploring both chemicals further and feel very fortunate to have experienced them. They have both been great tools for writing and introspection as well as giving me an oppurtunity to savor the beauty of myself, humanity, life, the world, and God.
