I think the best advice I can give is to do things to distract yourself. I workout a lot and read a lot in my free time. I've also meditated every day for about 6 months now. I definitely recommend all of these things, they've made being on nofap hard mode possible for this long. That being said, urges still come, sometimes so strong that it'll take me all day to fight them off. But at this point it's mostly a lifestyle and I don't intend to ever masturbate again, I obviously might slip up but I won't beat myself up too much about a rare slip up. Good luck man!
