Struggling with NoFap, need tips?

M here in his 20s and I genuinely want to stop watching p*rn and focus on my life. It makes me feel like I've no control over myself, like can't I even get over this one habit? I feel like my mind is getting adjusted to shit that shouldnt be normalized. I've tried controlling myself and the maximum number of days I could withhold is 9 days. Does going to the gym help in any way? Would genuinely appreciate if somebody could give me some Practical tips🙏
