The answer is that dopamine does not score what felt good. It scores what your brain did not see coming, and that one correction rewrites what a craving is, what a relapse is, and why a good explanation never fixes either. https://www.youtube.com/embed/P7MOz9tDXqQ 515 2026-09-18T07:04:05-07:00 yes no no https://thedopaminebrain.com/supplements/chapter-3/ https://i.ytimg.com/vi/GxR2Q7ZzTKg/maxresdefault.jpg Your Brain Priced the Job and Said No | The Dopamine Brain, Chapter 3 I hear the same sentence in my clinic every week: I know what I need to do, and I still can't make myself.
