Sorry to resurrect such an old thread but I want to share my experience
I finally got around to trying 2C-I a couple of days ago after having some in my stash for I don't even no how long. I took ~25mg on an empty stomach (I meant to eat beforehand but forgot to - I then tried to down as much of an instant ramen as I could) around 12:30PM and felt it come on around 1PM. I was expecting it to take longer to feel anything, must have been due to my empty stomach. In reading through people's experiences with 2C-I I saw several statements that the bodyload is light and nausea is uncommon. Well I couldn't even eat my whole cup of instant ramen before getting super nauseous and throwing up not once, but twice. This is a bit unusual for me because I do often get nauseous on psychedelics others than LSD, but it usually passes without me vomiting. I also noticed a feeling of electricity or slight tremors in my body. I read on here that a lot of other people experienced that during the comeup so I was not worried at all, nor was it completely unpleasant.
Anyways, after the second upchuck I finally felt better stomach-wise and the trip really started to unfold. I had strong visuals but not in the patterning or melty variety, more like lots of colors and tracers. I drew a little bit and it was fun to play with colored pencils (usually when I do draw I stick to pen) and let the tracers guide my art. I put some clips of Tipper sets on my tv and they sounded amazing. I mean, I already love Tipper but at some points I was literally snapchatting my friends bits of the sets as if I was actually at a show. The visuals he has for his sets were perfect in the moment as well.
My mind was relatively clear; I wasn't bogged down with memories that make my feel guilty (like 4-AcO-DMT) or stuck in my thoughts (like 2C-E). One of the things I enjoyed the most throughout the trip was talking to my friends via my phone. A bunch of my friends and I are in a group chat on Snapchat, and two of my friends also decided to trip on the same day in their respective phones. So we were all sending each other ridiculous pictures/videos/etc and I loved the absurdity as well as the sense of connection. Even browsing Facebook was fun, although I only did it for a bit before getting distracted, and I'm not usually one to use my phone much while tripping.
I spent a good part of the trip watching Dr. Strange for the first time, which was the perfect movie to put on while under the influence of psychedelics. Seriously, if you guys haven't seen it yet, take your trippy drug of choice and watch ASAP. It's basically DMT: The Movie. To the point where it made me deeply consider smoking some deems, but I didn't get around to that.
I also spent some time playing with my hoop and fire fans, and it felt really good to flow. I felt like I was close to unlocking some new moves but unsurprisingly would get distracted before long and end up doing something else. Food was also delicious once I remembered that it existed. Some psychedelics make me the opposite of hungry for the entire trip, but on 2C-I I could eat after only a couple hours into the trip. I made a very simple tofu meal but it was still super satisfying.
The trip last around 5 hours, a little shorter than I was expecting. I still felt off from baseline for a few hours after but the visuals and magic were definitely gone. The comedown itself was neutral to unnoticeable and I just felt content from having a very nice day hanging out with myself and my cat. Solo trips are so important and I don't give myself enough opportunities for them. This one was timed just right as I am beginning my second semester of graduate school next week so it was like a way to cleanse my mind before jumping back into that. Overall this was a very pleasant chemical other than the nausea on the comeup. I would take this at a festival but maybe start the trip at the campsite or in an open space in case I need to run to a trashcan/porta potty.
