Ten hazardous drinkers (4 women) who did not fit criteria for alcoholism, but who frequently drank at least 4 drinks per occasion (3 for women; NIAAA, 2007; Dawson, 2000; Dawson et al., 2005) were recruited from the community (Table 1). All voluntarily signed informed consents approved by the Institutional Review Board of the Indiana University School of Medicine. The subjects’ responses on the Time Line Follow-Back Interview for drinking (Sobell et al., 1986), reflecting the 3 months immediately prior to study enrollment, showed the sample to have a mean of 21.42 (SD = 5.06) drinks per week, 5.9 (SD = 2.3) drinks per drinking day, and 1.64 (SD = 0.65) risky/hazardous drinking days per week (min = 0.6, max = 2.5). Men and women did not differ significantly in either drinking pattern or family history. Five subjects had a positive family history of alcoholism (two or more first- or second-relatives with probable alcoholism) as assessed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA; Bucholz et al., 1994). The sample’s average score on the Alcohol Use Disorders Identification Test
