For me I think that focusing on the number of days is a trap. Once you internalize that you can only make it so many days without it your cravings only get stronger when you get close to that deadline. Try to remember that porn doesn’t add anything to your life, it only robs you of time and chances for real connection. Instead of thinking about how many days you can go without it try to imagine what you can gain from just not having it in your life. This journey can be hard but there is so much to gain and it’s worth it!
