Contemporaneous TAC/BrAC measurements were collected in a subject during three drinking sessions. After a fast of at least 4-hours, a subject (the author) drank a mixture of orange juice and 80-proof vodka ad libitum during a 5-minute period. BrAC measurements began 15-minutes after the end of drinking to ensure residual mouth alcohol did not bias the BrAC measurements \cite{Anstie1867-pr,Gullberg1992}. BrAC measurements were taken approximately every 16 minutes. Transdermal alcohol measurements were recorded every 20 seconds. A total of 43 Contemporaneous TAC/BrAC measurements were analyzed from three drinking sessions lasting 1.4, 2.0, and 8.1 hours.
