Making a solid attempt to quit this year. I think I've finally managed to close almost all the remaining loopholes I've found. I've been using Detoxify and Purity, in combination with Block (to block Chrome/YT 24/7 and the Play Store at night). I also physically restrict access to certain devices at certain times of day with the use of smart plugs and shutdown scripts.
What I learned is that the compulsion is ridiculously strong. I also learned I don't really miss it. Like... I'm ok without it. Addictions never feel that way, that's what makes it so hard to quit, but in reality it's been really nice to feel OK without it. It's also been much better for my marriage. Honestly even usage once a month is problematic I have found.
Years ago I read chapter 4 of "The Brain That Changes Itself" as that chapter is all about porn. It really opened my eyes. Glad I'm finally getting it sorted. I found it seriously worth kicking it out of my life.
