In the first two weeks the brain is most susceptible to temptation because the neural pathways associated with the addiction are stronger, because they have been recently activated.
Go a few months without activating them, and they will be significantly weakened.
These pathways have been reinforced over time through repeated behaviour, making it easier to fall back into old habits. During this period, urges may feel stronger as the brain craves the dopamine spikes associated with fapping.
This is why it’s important to stay vigilant, employ strategies for self-control, and build new, healthier habits that weaken the old pathways over time.
