Probably about half time in the city at clubs and parties, and half time out in the forests and remote beaches.
Strawberry double dips were prevalent, a few other designs, microdots etc.
I'm pretty sure it gave me a perspective still today, that I would not otherwise have.
I don't think it caused any "damage". I still graduated with one of the hardest 4 year degrees and went on to use the degree in a career. I don't have any regrets about it all and the events that unfolded.
There were, however, many, many notable incidents and events, most of them more than little bit funny, even today.
I don't really remember expressly how, why it ended, it was like organic decay. I think it just ran it's course with availability of LSD, us having the time and places to do it, and eventually I think life just took over.
But, definitely, there were some regular repeat customers.
But maybe the guy was a bit weird and produced more than was actually needed.
