Experience: 18 mg 2C-I - Visually intense and strong bodily sensations

11:00 – ingestion of 18 mg 2C-I.

11:30 – First noticeable onset; subtle bodily sensations. Come up over following 30 min. Bodily sensations increased in strength significantly; harsher than 2C-B with a strong component of nausea. I narrowly avoided vomiting.

12:00 – Approaching peak. Feelings of nausea gradually subside over following 30 min. First signs of visual distortion: my hands became partly translucent, appeared to age and wrinkle and I could see blood vessels writhing underneath the skin. The hairs on the back of my hands began to dance downwards like a waterfall, moving in time to my music. Level 4 visual geometry, particularly visible on my walls; these appeared to be covered in patterns of Mayan style which gently oscillated and rotated. My wooden computer desk became covered with a holographic layer of wooden spiral patterns; these also rotated in time with the music.

13:00-15:30 – Peak experience. Visuals reminiscent of 2C-B, of an intensity intermediate between 18 mg and 36 mg doses. Bodily sensations stronger than 2C-B, but difficult to characterize; overall a less pleasant body high, but far from dysphoric. When I looked at my face in the mirror, I appeared grey with visible blood vessels, reminiscent of a Sith Lord from KotOR. I experienced significant pupil dilation, as typical of serotonergic drugs. A discolored region on my wooden bathroom floor transformed into Mayan religious art; the eyes in the wood of my apartment floor became all-seeing. I was confronted in my kitchen by a pair of all-seeing eyes of judgment, and was unable to determine whether their gaze approved of me.

This was not as introspective an experience as LSD or psilocybin. However, there were some novel associations of ideas: for example, memories of a work colleague's back-and-forth hand motions became a metaphor for the seemingly meaningless fluctuations in the global political order.

15:30 – I went outside. Pupils still dilated but visual intensity greatly reduced. Pleasant feeling of residually high serotonin level – gentle buzz in mind and body. Gradual comedown over the following ~2 h; baseline consciousness achieved sometime between 18:00 and 19:00.
