There is a subreddit [1] about this where you can get a lot of suggestions and help.
As suggested before, breaking out of your bad habits is a great way to get started:
- never find yourself alone in a room with your computer (put the desk in the living room, etc.)
- get an app like Loop habit tracker [2] to track your "porn free" days and keep the streak going!
- do more activities with your loved ones (any kind of activities)
(I'm currently 65 days in. I know how it feels. It gets better with time. The fact that you've reached for help means you're already on the good way! Good luck to you!)
