meet criteria for alcohol abuse or dependence and drank less than 20 drinks/week. However, we maintained our previous criteria of requiring FHN women to be light drinkers because we have previously shown differences in the response to alcohol between light and moderate female drinkers (Evans and Levin, 2004) without a first-degree family history of alcoholism. Women who smoked cigarettes or used marijuana occasionally (< 1 time/week) were eligible. Individuals who consumed > 4 cups of coffee/day (the frequency and amount of all sources of caffeine use including coffee, tea, soft drinks and energy drinks was converted to cups of coffee/day for a standard reference) were excluded. None of the participants suffered from premenstrual dysphoric disorder based on the Premenstrual Assessment Form (Halbreich et al., 1982) and the modified Daily Ratings Form (see Evans et al., 1998 for details) that participants completed each evening throughout the study.
