Acid altered my perception for years, I still get visuals and tracers, apparent the molecules lurk in your synaptic gaps pretty much forever. I also couldn't leave the house for months, friend and I had a really bad trip one night on far too much acid, all plans went wrong, we ended up having to walk home 4 miles along a dark highway and got beat up halfway back, never known fear like it. I could only get over the anxiety of being out if I got good and drunk first.
