Study Description: Effect of Alcohol on Sleep and Daytime Performance

Nature and Purpose of the Study
This is a study of the effects of alcohol on sleep and performance. A study questionnaire follows the description of the study.

Explanation of Procedures
If you are eligible after completing the study questionnaire, the next phase of the study involves coming to the sleep research lab for an in-person study screening session. During this screening session you will complete forms, provide breath alcohol, a urine sample, and meet with a trained study team member who will ask you questions about your mood, current and past alcohol use, and as well as other questions. You will also be asked to provide a blood sample at a Lifespan lab location convenient to you. This screening session will help determine if you are eligible to enroll in the full study.
The full study requires you to follow a set sleep schedule for about 18 days and come to the lab on 2 separate occasions for 3 consecutive nights sleeping in the lab followed by 3 days of testing at your home or work. While at the lab your sleep will be monitored using standard sleep laboratory procedures using small electrode sensors attached to you to monitor sleep. On each night during each of these two in-lab sessions, you will be given beverages before sleeping. On one week you will be given a mixer beverage [e.g., sugar-free powdered drink]; for the other week session, you will receive the mixer beverage plus alcohol. During the inlab nights your bedtime is moved 3 hours later on all nights and waketime is at your usual time on the first night, and 2 hours later all the other nights. Throughout the study you will wear activity monitors. You must limit caffeine and abstain from drugs and new medications for the length of the study. You must also abstain from drinking alcohol except for the 3 nights during the in-lab sessions when you will be given the study alcohol beverage. You must be at least 21 years old, in good health, without a sleep disorder, and routinely drink alcohol.

Compensation
You will receive compensation for the time and effort involved in this study. The amount you receive is dependent on the amount of the study you complete. If you complete all aspects of the study you will receive a total of $1,010.
