It wasn't enormous, but it was my first time on shrooms after trying several other psychedelics. I don't remember the exact dosage, I think I had ground it up and put it in some small capsules to make measuring doses easier but I don't think I ever tried the rest since the first wasn't very pleasant. But like I said, people react differently, brain chemistry is complex.
Anyway, I far preferred the feel of LSD. But I haven't taken either in many years at this point, I don't have enough free time for it, lol. My main problem with all of them is the time investment.
I was going to make a comment about the 1998 battlezone game, but I looked it up and it's actually soviet moonbases, which makes more sense, really.
