Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Factorial Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The combination of ondansetron and olanzapine will be safe and superior to placebo at decreasing self-reported heavy drinking among early-onset alcoholics.
