If someone feels compelled to drink 3 drinks or more every day and is uncomfortable when alcohol is unavailable, they may have an alcohol dependency problem. The Dietary Guidelines for Americans 2020-2025 states that moderate drinking equates to 2 drinks or less per day for males and 1 drink per day or less for females.
According to the NIH, "heavy drinking" equates to:
For females: 4 or more drinks on any day or 8 or more per week
For males: 5 or more drinks on any day or 15 or more per week
