If you’re asking yourself this question, that awareness alone is meaningful. About 1 in 10 Americans ages 12 and older met the criteria for alcohol use disorder (AUD) in the past year, making it the most common non-tobacco substance use disorder in the country. You don’t need to hit rock bottom or drink every day to qualify. AUD is diagnosed when someone meets at least 2 out of 11 specific criteria within a 12-month period, and those criteria cover a wide range of behaviors and experiences that many people dismiss as “not that bad.”
The 11 Signs That Define AUD
Clinicians use a checklist of 11 symptoms to determine whether someone has alcohol use disorder. These aren’t abstract clinical concepts. They describe real patterns you can recognize in your own life. In the past year, have you:
- Ended up drinking more, or for longer, than you intended
- Tried to cut down or stop drinking more than once and couldn’t
- Spent a lot of time drinking, or recovering from drinking
- Wanted a drink so badly you couldn’t think of anything else
- Found that drinking, or being sick from drinking, interfered with work, school, or family responsibilities
- Continued drinking even though it was causing problems with family or friends
- Given up or cut back on activities you once enjoyed in order to drink
- Gotten into situations while drinking or after drinking that increased your chance of getting hurt (driving, swimming, unsafe sex, walking in a dangerous area)
- Continued drinking even though it was making you feel depressed or anxious, or adding to another health problem
- Had to drink more than you once did to get the effect you wanted
- Experienced withdrawal symptoms when the alcohol wore off, such as trouble sleeping, shakiness, nausea, sweating, a racing heart, or restlessness
If two or three of these apply to you, that qualifies as mild AUD. Four to five symptoms indicate moderate AUD. Six or more place you in the severe range. Many people are surprised by how low the threshold is. You don’t need to be physically dependent on alcohol to meet the criteria.
Two Quick Self-Checks You Can Do Right Now
The CAGE questionnaire is a four-question screening tool that takes about 30 seconds. Ask yourself: Have you ever felt you should Cut down on your drinking? Have people Annoyed you by criticizing your drinking? Have you ever felt Guilty about your drinking? Have you ever had a drink first thing in the morning to steady your nerves or get rid of a hangover (Eye opener)? If you answer yes to two or more of these, that’s considered clinically significant and worth following up on.
A more detailed tool called the AUDIT (Alcohol Use Disorders Identification Test) uses 10 questions about your drinking patterns, dependence symptoms, and alcohol-related problems. A score of 8 or higher suggests hazardous or harmful use. Your doctor can walk you through this, or you can find it online through the National Institutes of Health.
What Counts as a Drink
Before you can honestly assess your drinking, you need to know what “a drink” actually means. In the U.S., one standard drink contains about 14 grams of pure alcohol. That’s 12 ounces of regular beer at 5% alcohol, 5 ounces of wine at 12%, or a 1.5-ounce shot of spirits at 40%. A large pour of wine at a restaurant is often 8 or 9 ounces, which is nearly two drinks. A strong craft beer at 8% in a pint glass is closer to two drinks as well. Many people undercount by half without realizing it.
Binge drinking is defined as reaching a blood alcohol concentration of 0.08% or higher, which typically happens after about 5 drinks for men or 4 drinks for women within a two-hour window. If that pattern sounds like your typical Friday night, it’s worth paying attention to, even if you don’t drink during the week.
Physical Warning Signs Your Body May Be Showing
AUD doesn’t always announce itself with dramatic symptoms. Some signs are subtle enough that you might attribute them to stress, aging, or poor sleep. But your body keeps a running tab.
Tolerance is one of the earliest physical markers. If you need noticeably more alcohol to feel the same effect you used to get from two or three drinks, your brain has physically adapted to the presence of alcohol. That adaptation is not harmless. It means your nervous system now treats alcohol as part of its baseline chemistry.
Withdrawal is the other side of that coin. When someone who drinks heavily stops abruptly, symptoms can appear within hours: trembling hands, sweating, insomnia, anxiety, nausea, and a racing heart. These typically peak around 72 hours after the last drink. In severe cases, withdrawal can cause seizures (usually between 8 and 48 hours after stopping) or hallucinations. If you’ve ever felt shaky or anxious the morning after drinking and found that another drink calmed those symptoms, that’s a withdrawal cycle in action.
Heavy drinking also shows up in blood work. Liver enzymes called ALT and AST rise after heavy consumption and can stay elevated for two to three weeks. Another enzyme called GGT is even more sensitive to sustained heavy drinking, remaining elevated for two to six weeks. Very high levels of ALT and AST (around 500 units per liter) can indicate alcohol-related liver damage. Your doctor may notice these markers during routine lab work before you notice any symptoms yourself.
Why the Line Between “Normal” and “Problem” Feels Blurry
Alcohol use disorder exists on a spectrum, and that’s exactly what makes it hard to self-diagnose. The old model drew a sharp line between “alcoholic” and “not alcoholic.” The current framework recognizes that someone with mild AUD and someone with severe AUD have very different experiences, even though both have a diagnosable condition. You don’t have to lose your job, get arrested, or drink in the morning for your relationship with alcohol to be clinically problematic.
Over half of U.S. adults say someone in their family has struggled with AUD. That level of familiarity with problem drinking can paradoxically make it harder to see in yourself. If your drinking looks moderate compared to a parent or sibling who drank much more, it’s easy to tell yourself you’re fine. But AUD criteria are based on what alcohol does to your life and your body, not how your intake compares to someone else’s.
What Treatment Looks Like
If you recognize yourself in several of the criteria above, the path forward isn’t one-size-fits-all. Treatment typically combines some form of behavioral support with, in some cases, medication.
Three medications are commonly used to help people reduce or stop drinking. One (naltrexone) blocks the pleasurable effects of alcohol so that drinking feels less rewarding. It’s available as a daily pill or a monthly injection. Another (acamprosate) helps reduce the lingering discomfort and cravings that persist after someone stops drinking. A third (disulfiram) causes unpleasant reactions like nausea and flushing if you drink while taking it, creating a strong deterrent. These medications work best alongside therapy or counseling, not as standalone fixes.
Behavioral approaches range from one-on-one therapy to group programs. Cognitive behavioral therapy helps you identify the situations and thought patterns that trigger drinking. Motivational interviewing helps if you’re still ambivalent about changing. Support groups provide ongoing accountability. Many people start with their primary care doctor, who can screen you, order blood work, and refer you to a specialist if needed.
For people with severe physical dependence, stopping drinking abruptly can be medically dangerous because of the seizure risk. A supervised detox, usually lasting a few days, ensures safety during the withdrawal window. This is specifically important if you’ve been drinking heavily every day and experience physical symptoms when you skip a day.
Mild AUD Is Still AUD
The most common reason people don’t seek help is that their drinking doesn’t look severe enough to warrant it. But mild AUD tends to progress over time, not resolve on its own. The same tolerance that lets you drink more comfortably now is training your brain to need more later. Addressing it at the mild stage, when you might only need to make behavioral changes or work with a therapist for a few months, is far simpler than waiting until the consequences stack up. The fact that you searched this question means some part of you already has the answer.
