I've taken between 350 to 400 trips on LSD. This was back in the 70's. I still have flash backs today. The best thing I can tell you is let it alone. IT NEVER GOES AWAY. I see things every day and at 56 years old I get tired of triping. I haven't done any drugs in 30 years. I know every day that I get up I'm going to have some kind of a trip.
