First hints appeared within half an hour, but full effect took nearly three hours to develop, climbing smoothly with zero bodily discomfort and a running sense of humor. Sexual response was excellent and unhindered, with the writer's own orgasm delayed until the fifth or sixth hour but exceptionally satisfying, and a second following later. The state was gentle, good for writing, only mildly visual, and free of any dark undertones; the writer planned to try a higher dose.
