I don’t always want my wants either. The point is that needs usually produce greater motivation. The alcoholic who really wants that drink describes it as a need and works to satisfy it as if it is.

Alcoholism is a disease and addiction. They feel physical withdrawal so alcohol is a need to an alcoholic.

It's sometimes hard to see that because alcoholism is a spectrum and people joke about being alcoholics. Dismissing alcohol as a vice is not unlike dismissing an autistic as overly sensitive.
