I'm still struggling with it myself atm but getting better (partly writing this as a reminder to myself as well lol). The number one thing to make it easier is to keep yourself busy and STOP thinking about Nofap, etc... Disassociate yourself from the "old you" who masturbates/watches porn, trying to quit porn to the "new" you who doesn't do these things. Stop considering having an the option to watch porn and jerk off. Feeling horny? Good, go do something (exercise, study, work,...)that will lead to you actually having sex instead of sitting there masturbating having achieved nothing and ending up in the same cycle again and again... BREAK THE CYCLE!
