Some days a slave - Some days a king

Hello everyone,
So far my nofap journey is accounted as :-
Post-masturbation to my fantasy, numb for a while than i'm full of regret. Later on, watching recovery videos, reboot content things get in order.
A week or two goes pretty fine, then all of a sudden - whether i'm in middle of something or sitting idle, a thought pops up in mind.
I decide not to go with it.
It comes again and again.
I just sit back and relax saying - You have all the freedom to come and go as i don't exercise control over you, but i choose what i wanna do. I won't do what you say.
The urge dissipates.
But the problem arrives when within a few days, my body and mind start asking for pleasure. The cravings for got a bit subtler. It then repeatedly asks for that squirt of dopamine, that relaxation with high.
But as everyone knows, this is just part of that horrible cycle to make oneself far more miserable.
Please help me out.
