Summary

This study looks at how men and women react differently to two weeks of not drinking alcohol. Researchers will measure alcohol intake, brain responses, and personal feelings after the break. The goal is to use this information to create better ways to prevent and treat alcohol use disorder. About 160 moderate social drinkers will take part.
