Hangover, Congeners, Sleep and Occupational Performance

• Status: Completed
• Trial end date: 2006-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The objective is to investigate residual effects of heavy drinking, with or without hangover symptoms. The primary aim is to test several hypotheses about residual effects of heavy drinking. Hypotheses about how heavy drinking affects next-day performance include direct physiological effects of alcohol, alcohol withdrawal effects, and non-ethanol effects, such as congeners, or family history of alcohol problems. The investigators will test the following hypotheses:

1. relative to placebo, heavy drinking will degrade next-day performance, and this relationship will be mediated in full or in part by quality of sleep;

2. a high congener alcoholic beverage will affect performance to a greater degree than a low congener beverage and this relationship will be mediated by severity of hangover symptoms.
