Hi Hershey,
I can tell you my experience and the advices I caught from it. Don't take it as the hidden revealed truth, because it might not fit with you!
I think that what you have begun to do is ok, but it can prevent you from PMOing during the day, not when you are on your bed, eventually alone.
I started beign very motivated doing nofap when I deeply undetstood how porn is harmful. So the very first step is getting educated on the topic. Checking Gabe's video and reading the book "your brain on porn" will be fine. You must be disgusted by the idea of PMOing (unluckily, the feeling of disgust lasts less than the urge...!).
After that, get busy as much as possible. Avoid thinking and any trigger you could meet!
Stat away from home, workout and stop your brain to fantasize on porn or having sex!
I hope this could help.
Good luck, bro
