The number of inhalations is variable, but I prefer to try to get it all in one hit if possible. The effects come on fairly quickly, beginning within 30 seconds, the full effect occurring by c. 60 seconds. First time was three years ago, last time was this evening. I always smoke it, except one attempt at snorting 20 mg, with little effect.
Time of day is irregular, but lately usually early evening.
Effects have been too variable to notice correlations with time, if any. I have thought of looking for a correlation with the phase of the moon, but have not done this. I generally smoke it alone, since colleagues in this area are not numerous. As noted, the effects come on quickly, and I'm swept away. After taking the last hit I lay back and close my eyes and try to observe what's happening.
