I had a similar experience, too. I was 18, just before starting college. It took me about 15 months to start to recover with Prozac helping me create breathing space. Daily flashbacks. It took about 4-5 years for the flashbacks to stop. I stopped marjuana/cannibis during that time, tried it again 10+ years after the event, could handle it then. LSD is dangerous, even once taken in the right environment can screw you up for life. I had a long road back, screwed up my first 3 years in college (went from top of class in high school to average, but recovery in year 4 meant i ended up back top-of-class). Still, terrible drug.
