This actually happened about 12 hours ago. I'd been sitting on a gram of 2cb for a while now, looking for an a good time/mindset to take some. I had only taken 2cb once prior with my girlfriend (~18mg orally in a gel cap. They experienced great visuals while I had some akin to ~75ug of LSD. Granted I don't get many visuals on psychedelics to begin with. We both had horrible nausea though and were confined to their bed for the duration of the trip).
To combat this nausea, I decided to research different ROA's. Since I hate snorting things, plugging was the only way to go. I was originally planning on plugging only 15mg, however I must've scooped to much out of the bag, and ended up with 19mg on my scale. I didn't want to deal with fumbling and struggling to put the extra 4mg back in the bag, so I decided to go with the entire 19. I dissolved it in 1mL of water, and drew it up into the syringe, and I took the plunge.
After laying on the floor for a few minutes, coming to terms with what I'd done, I stood up, and with immediately overcome with the worst urge to shit in my entire life. I had gone beforehand, so I just assumed it was the water stuck in there. I then decided to wobble over to my bed and lay down. After staring at the ceiling fan blades, the clumps of dust started to "flow" to the edge of the fan blade in classic psychedelic fashion. I was caught off guard by how fast I was starting to come up, I'd plugged it no more than 10 minutes ago. After a few minutes of watching the fan and researching if I could take a shit, I went back to the bathroom and finally took one (again).
Finally I could begin my trip. I nestled in my chair and put on a season of adventure time that I'd downloaded specifically for this trip. I couldn't focus on it though, as my body had this constantly unease, almost like it was jittery and cramping. This all came to fruition when I had to rush to the bathroom (again) to dry heave two or three times. Nothing came out. This was about the end of the unbearable body load. I resumed adventure time, and throughout the episode, I kept seeing vague patterns appearing on every surface. They were very faint but they reminded me google deep dream
This was about the peak of the visuals, I wasn't blown away, and I got absolutely no CEVs, which kinda disappointed me. After about 3 or 4 episodes, I noticed all of the visual effects were gone, and the only remaining effect was the head "spaciness" that comes with most trips. I knew plugging shortened the duration, but not by this much.
My second 2cb trip was okay at best, I expected more, but I was caught off guard by the horrible body load. I may try it again at the same dose sometime in the future.
