adequate to ensure accuracy; furthermore, no differences in weight between groups were observed during the course of this study. Ethanol consumption was measured after 6 hours and again after the next 18 hours. Measurements made after the next 18 hours are presented as percent of corresponding control. Measurements of ethanol intake, preference, and total fluid intake were averaged over 2-day periods with different bottle positions. Each point in the graphs (days 2, 4, 6, etc.) represents the average of 2 days of measurement. For example, day 2 is the average of days 1–2 after saline for both control and drug groups; day 4 is the average of days 3–4 after saline or drug, and day 6 is the average of days 5–6 after saline or drug. Ethanol intake, preference, and total fluid intake were also calculated after 24 hours in the two-bottle choice test.
