Hi everybody.
Saw some interesting things on this site so decided to join.
I did acid about 6 times nearly 30 years ago and still have some tracers(persistence of vision) and once in a while I get the spiral effect if I look at at patch of concrete or grass. Anything with kind of a regular pattern to it.
Antidepressants have removed some of the HPPD symptoms, and I believe tricyclics made them worse.
Right now I'm dealing with something that happened three years ago. I noticed that the "halos" I saw around lights were gone. I also got more depressed, anxious, and paranoid nearly the same day. I've cried very easily since then and can't work. Kind of a bummer. I remember when halos went away one other time in my life, and they came back due to the use of antidepressants then.
