Most people who try to quit something fail in the same way. They white-knuckle the first week. The body fights. The mind negotiates. By day twenty-one they have rationalised one slip. By day thirty they are back at the beginning. They conclude they lack willpower. The conclusion is wrong.
Willpower is a depleting resource. Identity is not. The Sikh framework for quitting does not run on willpower. It runs on identity replacement. The person who could not quit the habit is replaced, gradually, by the person who no longer has the habit. Same body. Different self. The habit has nothing to attach to in the new self, so it falls away.
This framework has been used by the Khalsa for three centuries to replace identities at scale. It works for tobacco. It works for alcohol. It works for pornography. It works for compulsive eating, compulsive spending, compulsive arguing, compulsive scrolling.
