  Purpose

The purpose of this study is to determine whether: (1) the combination of N-acetylcysteine + high-dose naltrexone (150 mg) works better than high-dose naltrexone (150 mg) alone in reducing alcohol drinking; and (2) high-dose naltrexone (150 mg) alone works better than low-dose naltrexone (50 mg) alone in reducing alcohol drinking.
