I spent an hour reading this thread and I still have no idea whether I should try it or not. I always leave confused when I read about LSD, as if it's both amazing and horrible.
As someone that's done it (a dozen or so times), I always read these threads and feel confused about whether I should recommend it to other people. I usually do recommend it, though, with plenty of caveats.
It can be an incredible experience if only for the shift in perception that it causes. It makes you see that the way your mind operates day-to-day (through highs, lows, and in-betweens) does not even come close to the range of experience that's possible.
It can be euphoric, and it can be scary, and depending on your predispositions it can probably improve your life significantly (given that you integrate insights from your experience into "normal" life), or really mess with your head (esp. if you have latent schizophrenia or similar - I'm admittedly pretty ignorant about this so obviously do your own research).
Anyway, my recommendation to people using it for the first time is to start with a low dose (you often won't even realize it's having any effect until after the trip is over – I didn't believe it my first time), make sure you are in a safe place where you can be left alone to relax if you need to, and ideally make sure to have someone with experience & that you trust to spend time with you and guide the trip.
