What are the misconceptions about controlled drinking?

The host asserts that the concept of 'controlled drinking' is a myth. Once a person crosses a certain threshold of alcohol dependency, they cannot simply return to moderate drinking. Alcoholism is described as a progressive disease, meaning that once someone has developed a dependency, it is unlikely they can return to a non-dependent state without significant effort and lifestyle changes. The host emphasizes that if a person feels the need to exert willpower to avoid drinking, they likely already have a dependency.
