Note: Baseline meaures come from the full Alcohol Purchase Task; bolded effects are significant at p<.05; Intensity = consumption at zero cost , Omax = peak expenditure for alcohol, Breakpoint = cost at which consumption is suppressed to zero; Overall there were 2625 (out of 2660 possible) daily assessment points
