After a foul-tasting start and two hours spent consciously fending off nausea, the writer found faces looked like wonderful caricatures of themselves and time seemed markedly slowed, with no appetite at all. The mental effects drifted off between the eighth and twelfth hours, but the body stayed keyed up: sleep was impossible until the eighteenth hour, and the next day brought hyperactivity, alertness, excitement, no appetite, and intermittent diarrhea. The writer judged it a powerful stimulant with a strong adrenaline-like drive, with tension finally releasing into easy sleep only the second night.
