I've been "feed free" for over two years now. Took a while, but damn is it a better life!!!!

Didn't matter if it was news, social or whatever, it messed with my dopamine apparatus, as Gabor Mate calls it.

I do limit my self to the first page or two of the HN feed though, to keep up on tech developments for my career, which I still have to be careful about.

It's feeds in general. It leads to abnormal dopamine release which affects motivation.
