Almost every quit guide treats the question as if it were about strength of character. The Stack starts from a different premise: the people who quit successfully are not the ones who wanted it more. They are the ones whose plan contained the right pieces.
If you have already tried to quit and it didn't hold, the most useful thing I can tell you is that the failure almost certainly wasn't moral. It was structural. One or two of the six components in the Stack were missing from the plan, and the gap is where the next cigarette walked in.
The successful quit usually isn't the one with more willpower. It is the one with the right method.
That is why this site has a framework page with a name. Not because the practice needs a brand — because you need a structure you can point to when the day goes sideways and the plan needs to hold. The Quit Stack is that structure. Six components. Each one named so you can call it by name when you need it.
This page is the map. Each component below is a station on it. Some of them will look obvious. Some of them will look unfamiliar. The ones that look unfamiliar are probably the ones the last quit attempt was missing.
