I only tried it once. The worst I can remember is finding out the next day that there were this very unhealthy substitutes (such as the N-Bomb) being sold instead of the real thing, so I can't tell if I took actual LSD. The experience was fine. It went through several stages. First it was visual, then more introspective. I felt something I can only describe as being dead, meaning that I felt very aware of being matter, and I thought of that beauty around us that is not alive and is simply indifferent and potentially destructive to life and any sense of purpose. Then at some point I was cleaning some fresh basil to prepare something to eat and I found a caterpillar among the leaves and carried it to the garden. The caterpillar jumped and I felt like an electric shock had gone through my body. Later, while sitting with my friend (also on LSD), I narrated this experience to my friend and I started crying. My voice sometimes sounded robotic to my ears.
