My main trigger is when I think about a certain porn scene or sub porn scene or a specific character or actress that I have pmo'ed to in the past. How can I counter this? After I haven't fapped in a few days, these scenes/characters become INSANELY attractive to me and I want nothing more than to fap to them. I'm in a sort of rut/slump right now and I can't get out of it. Every day I tell myself "Tomorrow I will get back into my workout routine, stop fapping, etc etc etc." I know that once I get unstuck, I will gain momentum and be high on motivation for a while, but I can't seem to do it. Everything is a double edged sword. NoFap, workouts, waking up early. They all help me substantially when I do them, but when I fail, I am crushed.
I get stuck in these "Tomorrow I will start" traps for months. I have been saying "tomorrow I will workout" for the last 6 weeks
That's really the whole point is to train yourself be the master of your own mind. Master of mind means, master body: it's impossible to PMO without the full consent of your mind. Rather than wearing yourself out on willpower, focus on alertness and speed instead. That means the moment, the second, and the millisecond one of these urges starts to creep into your mind, you firmly and quickly cast it away before it has time to take root.
Quitting is very tough. I have quit for long periods in the past and relapse ended up happening no matter what. It is kind over matter and it is a matter of knowing your triggers and avoiding those as much as possible. Keep fighting man.
