The amount of ethanol consumed by chronic alcoholics in a Japanese slum area with persistent insomnia (n = 40) and those without it (n = 40) was compared using a questionnaire. For both groups, the present habitual consumption (PHC) of ethanol per day was most frequently between 60 g and 150 g and no difference was observed between the two groups. In contrast, the maximum habitual consumption (MHC) of ethanol per day throughout the alcoholic history was found to be greater for the insomnia patients than the non‐insomniacs (p < 0.001). No difference between the groups was found in the kind of alcoholic drink consumed, with sake (Japanese rice wine) being the most popular in both groups. The results suggest that persistent insomnia in alcoholics is related to excessive alchol intake and persists even when drinking levels have fallen.
