Key takeaway
One hard weekend can feel like a diagnosis, or like a reason to quit with nobody watching. Binge drinking is a blood-alcohol pattern, often four drinks for women or five for men in about two hours. Alcohol use disorder is impaired control despite harm. Tell a clinician the pattern. Do not stop heavy drinking alone.

One hard weekend is sitting in your head as a diagnosis. Or as a reason to quit tonight with no one watching. Tell a clinician how much you drank, how often, and whether cutting down has already failed. Do not stop heavy drinking on your own.
If someone is seizing, unresponsive, or not breathing, call 911. For a mental health crisis, call or text 988.
A pattern is not the same thing as a diagnosis
NIAAA defines binge drinking as a pattern that brings blood alcohol concentration to 0.08 percent, or higher. For a typical adult, that often corresponds to five or more drinks for men, or four or more for women, in about two hours. Alcohol use disorder is a medical condition: an impaired ability to stop or control use despite social, work, or health consequences. It can be mild, moderate, or severe. One episode that crosses the binge line does not, by itself, establish that disorder. Repeated misuse does raise the risk.
A news story can use a different cut and call it the same word. SAMHSA's survey definition, quoted by NIAAA, is five or more drinks for males or four or more for females on the same occasion, on at least one day in the past month. If you are comparing a headline with a clinician's explanation, ask which definition is in the sentence.
A standard drink in the United States is any beverage with 0.6 fluid ounces, or 14 grams, of pure alcohol. The glass in front of you may be two. Counting cans will not tell you whether you crossed 0.08 percent. The adult figures are for a typical adult. Fewer drinks in the same time can produce the same blood alcohol level in youth. People younger than 21 should not drink.
A bad morning after is not the diagnosis. Read what a hangover is for that morning, and sober curious if the question is whether you want to drink less without a disorder. If most weekends look like this and work still looks fine, read high-functioning signs. If you are unsure the amount counts at all, read gray-area drinking.
When the next call is a clinician
Talk to a clinician when stopping or cutting down has already failed and work, health, or a relationship is paying for it. Talk to one when binge or heavy drinking is the usual pattern and you want that to change. You do not need a severe label to ask. Talk to one after a blackout, a crash, a fall, or a drive. The legal driving line NIAAA ties to 0.08 percent is the same blood alcohol level as its binge definition.
Talk to one if you are pregnant or might be. NIAAA says alcohol use in pregnancy raises the risk of fetal alcohol spectrum disorders. Talk to one if you take medicines that interact with alcohol, if you are older and the falls worry you, or if you have a condition alcohol makes worse. NIAAA flags each of those as a reason some people should not drink at all. Over time, repeated binge episodes contribute to liver disease and to several cancers. Read alcohol and liver disease if the liver is the worry. The wider picture is on the alcohol page.
A sudden stop after chronic heavy drinking can be life-threatening. Do not treat a calendar as medical advice. Read alcohol withdrawal for the red flags, the detox timeline for what the hours can look like, and detox at home versus a medical setting for why a home plan is the wrong tool when withdrawal can become severe. There is no taper schedule here.
Medicines for alcohol use disorder are a clinician's decision after the withdrawal question is settled. They are not something to start because a weekend went badly. What treatment can look like once you are in it is in alcohol rehab. You can also look through the NIAAA treatment navigator.
When you call, say how much, how often, and whether you have tried to cut down. Mention any blackout, seizure, shaking, or morning drinking. Mention medicines, and whether you might be pregnant. Ask whether you need a same-day medical check before a counseling appointment. Start the search in how to find treatment.
Search FindTreatment.gov. Call or text (800) 653-9376 if you want help finding an alcohol assessment.

Common Questions
If I binge once, do I have an alcohol use disorder?
Not by that fact alone. NIAAA defines binge drinking as a pattern that brings blood alcohol concentration to 0.08 percent or higher. It defines alcohol use disorder as a medical condition: an impaired ability to stop or control drinking despite social, work, or health consequences. Misuse over time raises the risk of that disorder. A clinician uses a set of criteria to decide whether it is present and how severe it is.
Why do NIAAA and SAMHSA describe binge drinking differently?
They are answering different questions. NIAAA's definition is a blood-alcohol pattern, usually five or more drinks for men or four or more for women in about two hours. SAMHSA's survey definition is five or more drinks for males or four or more for females on the same occasion, on at least one day in the past month. Ask which definition a number or a brochure is using.
What counts as a standard drink, and what is heavy drinking?
NIAAA says a standard drink in the United States contains 0.6 fluid ounces, or 14 grams, of pure alcohol; a large pour can be more than one. NIAAA defines heavy drinking as five or more drinks on any day or 15 or more in a week for men, and four or more on any day or eight or more in a week for women. SAMHSA defines heavy use as binge drinking on five or more days in the past month. High-intensity drinking is twice the binge threshold.
How does a clinician describe severity?
NIAAA's fact sheet follows the DSM-5 count. Mild is two or three criteria, moderate is four or five, and severe is six or more. A health professional applies that count. Two people can both binge and only one of them meet it. Youth reach the same blood alcohol level with fewer drinks: about three for girls, and three to five for boys, depending on age and size. People younger than 21 should not drink.
Can I taper at home from a schedule I found online?
No. There is no drink schedule here, and no medicine list or doses. NIAAA says a sudden stop after chronic heavy drinking can be life-threatening. Up to half of people with alcohol use disorder have some withdrawal, and a smaller share need medical monitoring. Call 911 for a seizure, collapse, trouble breathing, or severe confusion. Call or text 988 for a mental health crisis.
