there must be some other mechanism, as my brain is already blacked by the mentioned pigments. My "grey matter" -> is "black matter" now.

I did not go through psychosis episodes. Which doesn't mean, others won't. Now, that I've life long experience with, I would recommend fresh-mens to wait until 25th birthday - and then "it's your birthday, you can party like it's your birthday". If one did not start before that mature age, its likely never happen.

drink less, smoke more ;)
