I got a ceramic gravity filter and swapped in an anti-fluoride cartridge about a year back, but too much shit went down in the past year that's made me unproductive and unmotivated so it's hard to determine what the effect was. Around late 2018 I felt a sense of inner doom, a bit like my soul was crying out for me to do *something* to save my sense of individuality and that was what set me on that path, but if it was even related to fluoride I might have acted too late. Other factors that complicated things were that around that time my employer fell under bad management and did a few overbearing things, like forcing me to buy a smartphone for the first time to run a dumb and invasive app; most colleagues thought I was just being silly when I complained but it felt like over the course of a few months they broke part of my old free spirit on a deep level by crossing my personal boundaries, and I also watched certain occupations that once brought joy to my life being run down and destroyed by leftist busy-bodies at around the same time. I wanted to go back to the kind of person I was before and thought cutting fluoride might have helped detoxify my brain, but if I have more mental clarity now it's only the type that's made me aware of the sheer futility of things I used to enjoy spending my time on.
