2. T+03:00:00 [intensity]
intensity
± PLUS/MINUS — Threshold — something may be present, but it's right at the edge of perception. A stronger experience would confirm it; otherwise it may be nothing.
3. T+04:00:00 [intensity]
intensity
+ PLUS ONE — Clearly noticeable. You can tell when it began and how it's changing, though its full character isn't apparent yet.
4. T+00:00:00 [note]
Nothing happened for roughly three hours after ingestion. When effects finally arrived they were nearly devoid of visual change, instead sharpening intellectual activity in a way that felt more like a stimulant than a psychedelic, and less pronounced than psilocin. The writer found the ride distinctly unpleasant and had no interest in exploring further.
