I have taken LSD on probably about 288 occasions. Largely it has had a pretty neutral effect on my life, leaning towards positive. I experienced Ego death and it was quite beautiful but I don't think it was really life changing. I have gained some very deep introspection into my life , certainly aided by LSDs ability to cause me to vividly relive past experiences. I feel like it helped me to understand how minds work, and my own in particular. It has given me several experiences with God, someone who I never had had experiences with before but who I still do not believe exists, if that makes any sense. Perhaps it has helped me to fear death less , particularly from ego death experiences, but I am entirely unconvinced that I will really merge into eternity when I die (I strongly suspect that I will fade into oblivion, unfortunately. My biggest hope for eternal life was a cyclic universe, but unfortunately it appears that the universe will experience heat death.). I really have an appreciation for aesthetics that LSD may have increased, I certainly have obtained an understanding that things are far far more intricate and detailed than my sober mind allows me to perceive. I may have a new perspective on life from it, it is hard to say how much of who I am is from LSD and how much is just from myself growing up and changing separately of LSD.
I can't really think of any ways that LSD has negatively impacted my life. Maybe time I spent tripping instead of working and doing productive things, 288 acid trips literally translates into almost a year of time spent high and incapable of doing significant work.
I think I will probably continue using LSD until the day I die, at least once or twice a month, preferably four times a month and preferably not more than that. I have to admit that I sometimes take LSD hoping for a truly life changing positive experience, but LSD has not brought that to me and likely it never will. I view it as like going to an art gallery to appreciate aesthetics, except the art is nature and the LSD simply allows me to see it as such. It is like therapy in some sense, I am sure it has had a therapeutically beneficial effect on me. It is like a religious experience beyond a doubt, indeed it is a religious experience, but I am not a religious person and LSD has not convinced me away from logic anymore than Christians have, but it has certainly been far more agreeable and helpful to me
