Forty-five minutes after arrival, the participant completed baseline subjective and objective measures and then consumed his or her study beverage over 15 minutes (5 minutes for each portion separated by a 5-minute rest interval) in the presence of the research assistant.21,50,67 Subjective and objective measures were repeated during the ascending limb to the estimated peak BrAC (30 and 60 minutes, respectively, after beverage initiation) and the descending limb and alcohol elimination phase (120 and 180 minutes). The breathalyzer (Alco-Sensor IV; Intoximeter, St Louis, Missouri) was programmed to display readings of 0.000 mg/dL, with the actual levels later downloaded to a computer by a separate assistant. Between time points, to circumvent potential boredom, the participant was permitted to view movies or read magazines provided by the study in a comfortable, living room–like laboratory testing room. At the end of each session, when the BrAC was 0.04 mg/L (0.04%) or lower, the participant was transported home by a car service to ensure safety. At the end of the third session, the participant was debriefed and received instructions and schedule information for the
