Good old days eh. First time I took shrooms I was told "it's like weed, just stronger".
That story of yours is a cautionary tale I've lived too. I took an eighth or so (btw, who the F calls it a half quarter? lol, never heard that before), and immediately went for a shit. It was a bit of a mad scramble out the door after and a buddy of mine said something to the effect of "you just shit your mushrooms out!" and handed me the bag. In a rush I started eating a bunch more and basically realized as I was swallowing how dumb and uneducated that statement of his was. Epic night.
I had a good line on them for a long time. While most of that was for selling, we would just over indulge like idiots because there was so much around. I actively caution youth against such things because I feel like stories like ours are over doing it and probably wading in to some potential mental health consequences.
