Participants were instructed to abstain from alcohol and medications for at least 48 hours, as well as caffeine, cigarettes, and food for three hours prior to the session. When participants arrived (between 3pm and 5pm) they were provided a snack at 20% daily calories based on their body weight to reduce the possibility of alcohol-induced nausea, and to avoid hunger effects on mood state. This was followed by administration of the Biphasic Alcohol Effects Scale (BAES; Martin et al., 1993). The participants then consumed the assigned session beverage over a 15 min interval in the presence of the research assistant; the beverage was divided into two equal portions to consume over five minutes each, with a five-minute rest period between portions. The BAES was repeated at 30, 60, and 120 minutes after beverage onset. Breath alcohol concentrations (BrACs) were obtained using the Alco-Sensor IV (Intoximeter Inc., St. Louis, MO) at the same intervals, as well as other subjective and objective measures as part of the larger study. During portions of the session when measures were not being obtained, participants were
