A five-minute absorption period followed beverage administration, and participants then completed BrAC measurements and assessment of subjective effects every 5 to 6 minutes until BrAC reached 0.065% for alcohol participants (or after 1 BrAC measurement for placebo participants). At this time, a battery of cognitive tasks relating to the larger study was administered, and BrAC, BAES, and subjective intoxication assessments were re-administered after every other cognitive task (approximately every 20 minutes). Upon completion of the cognitive tasks, BrAC and subjective effects were assessed every 5 minutes until BrAC descended from peak to 0.075%, at which time the cognitive task battery was completed again; as during the ascending limb, BrAC, BAES and subjective intoxication were assessed after every other task.
