I remember that I was sole pioneer of tripping in my peer group in the mid to late 70s.
The first time I took acid, I took a hit of purple micro-dot and tripped all by myself for the next 14 hours or so. I did have some of my friends close by at the start and of course they had to fuck with me, trying to get me to freak out. lol I had to go home eventually and "sleep" lol. No sleep that night. Just a 15 year old kid in his bed alone, experiencing LSD for the first time. It was a magical, mesmerizing, and at times, scary experience. It lasted so long, and prevented me from sleeping even though I was extremely tired. That felt like torture. It was the longest "buzz" and I did wonder if it would ever stop, and more than worried that it wouldn't. But it did, and I woke up the next day with a entirely different outlook on so many things.
After my friends saw that I survived the trip, they all started doing it. We had some wild parties.
