I don't remember exact time I got it as I only abstained in 2018 which is when the link got clearer but remembering how many times I comprehended some stuff worse, was awkward and feeling odd postO I had it b4. When each O gave symptoms after abstaining it got clear cuz of O. 1st I thought all feel so, I found NoFap/SR 1st, only later by seeing how others don't got such brainfog, etc. I thought it must be physical reason not natural postO feeling so I accepted it's POIS in 2019. I put 2015-2020 as I think symptoms got strongest then.
