Ethanol intakes of high-alcohol-drinking-2 (HAD-2) rats initially deprived of alcohol for 2 or 8 weeks and then taken through cycles of 2 weeks ethanol access and 2 weeks ethanol deprivation for a total of four cycles. Baseline values were determined from the average of the last 3 days just before deprivation. A single asterisk (*) indicates that ethanol intake is increased over baseline levels following all deprivation periods and that intake following the third and fourth deprivation period is greater than following the first and second deprivation. Double asterisks (**) indicate that ethanol intake (a) is increased over baseline levels following all deprivation periods; (b) following the second and third deprivation is greater than following the first deprivation; and (c) following the fourth deprivation period is greater than following all other deprivation periods. Triple asterisks (***) indicate that ethanol intake (a) is increased over baseline levels following the second, third and fourth deprivation periods; (b) following the second and third deprivation is greater than following the first deprivation; and (c) following the fourth deprivation period is greater than following all other deprivation periods. A single plus (+) indicates that ethanol consumption following the third and fourth deprivation period is significantly greater than baseline intake values. Double pluses (++) indicate that ethanol intake is increased following the fourth deprivation period. Triple pluses (+++) indicate that ethanol intake is increased over baseline levels following all deprivation periods, and that ethanol intake following the second, third and fourth deprivation period is greater than following the first deprivation. A single pound (#) indicates that ethanol consumption is increased, following all deprivations cycles compared to baseline intake, and all deprivations cycles are different from each other. A double pound (##) symbol indicates that ethanol is significantly elevated, following the fourth deprivation period compared to baseline intake values
