For what it's worth ... I'm much older than most here and my advice would be to stay as far away from acid as you can get. I have no idea what it's like these days, but I used to do it in the seventies and it was pretty heavy shit then. I was an acid freak - absolutely loved it; one night things got pretty bad but I made it through - unfortunately I never learned a lesson from it. A couple months later three of us did some 'windowpane' (it was called) and all hell broke loose ... totally lost my mind so to speak ... suddenly found myself at the bottom of the carpet trying to climb out, up the fibers ... couldn't make it ... somehow ended up outside riding trees ... climb one, it springs into the air and tosses you over to the next one - so I thought ... ended up with a broken arm but didn't even know it 'till the next day - too busy trying to keep my head from turning inside out - really - inside out ... and these are only a couple of the nightmares that lasted for 14 hours - plus 10 years.
Yup, that horrific trip affected me for over 10 years. I constantly felt like I couldn't hold on to my thoughts, control my mind, that sort of thing. Over time it wore off, but like I said, it took over 10 years. During most of that time I couldn't even smoke pot or drink as they would trigger a flashback. Everything is fine now, in fact, I can hardly believe what I went through (found a good wife - that was the key for me.)
Incidentally, 3 of us did the windowpane that night, but one, my brother, ripped the tab in half to save half for another day, so he was all right; however, a friend who also did a whole tab (which was the norm) freaked out also. He had trouble for years too and still has flashbacks to this day.
I would hate to this happen to anyone else, it almost ruined my life. Shrooms were rare back then, at least where I lived, so I only tried them once without issue. I don't know much about them. Acid, on the other hand, I am an expert. I did hundreds of hits, and regret it to this day. Acid ruined my ability to concentrate and sort thoughts properly. If I were you, I'd stick to pot. I know many people who have smoked for over 30 years without any trouble. Acid, on the other hand, is a nightmare waiting to happen. It's your choice, but give it some real thought, and don't do it alone. Make sure there is a sober person there.
