Quitting and cutting back
How Much Alcohol Is Too Much?
Drinking guidelines by country, what counts as a drink, and a simple self-check to help you decide whether to cut back or get support.

Quick answer: there is no amount of alcohol that is completely risk-free. Weekly guidelines help you judge risk, but the amount in each glass, how much you drink at once, and whether drinking is getting hard to control matter too. You do not need to wait for a diagnosis to change a pattern you are unhappy with.
Maybe you only drink at weekends, but the weekends have grown. Maybe it is two generous glasses every evening, and you have stopped asking how generous. “Too much” sounds like it should be one number. In practice, there are two questions: how much alcohol are you drinking, and what is it doing to your life?
Safety first: if you drink heavily every day, or feel shaky, sweaty or sick when you miss a drink, speak to a doctor before cutting down sharply or stopping. Our alcohol withdrawal guide explains why.
Drinking guidelines by country
These are population guidelines for adults, not personal prescriptions. “Lower risk” does not mean no risk. Check the unit in the middle column before comparing countries: ten drinks does not mean the same amount of alcohol everywhere.
| Country | Alcohol measure | Guidance |
|---|---|---|
| United Kingdom | 8 g per unit | No more than 14 units a week, spread across 3 or more days. |
| Canada (CCSA, 2023) | 13.45 g per standard drink | 1–2 drinks a week is lower risk; risk increases above that. Avoid more than 2 on an occasion. |
| Australia | 10 g per standard drink | No more than 10 a week and no more than 4 on any one day. |
| Ireland | 10 g per standard drink | No more than 11 a week for women or 17 for men, with 2–3 alcohol-free days. |
| United States | 14 g per standard drink | The 2025–2030 Dietary Guidelines advise drinking less for health; they no longer give a daily numerical limit. |

The useful common ground is that less alcohol means less risk. If you are above a guideline, bringing your total down is worthwhile. If you are below it, you have not found a guarantee against harm.
Count alcohol, not glasses
“Two drinks” could mean two small beers or two cocktails with several measures of spirits. Start with the volume and the ABV on the label. Our guide to standard drinks and units has the formula and a table of common pours.
A 750 ml bottle of 13% wine contains about 77 g of alcohol: 9.8 UK units, 5.5 US standard drinks or 7.7 Australian standard drinks. Half a bottle each night is roughly 34 UK units a week. It can look like “just a couple of glasses” and still be well above the UK's weekly guideline.
Try measuring your usual home pour once. You are checking the starting point, not sitting an exam. Record the actual size and strength rather than the serving you think you should have had.
What about one heavy night?
A quiet week does not cancel a heavy Saturday. The amount you drink in one sitting affects immediate risks such as falls, injuries and alcohol poisoning. Weekly totals miss that pattern.
The UK advises spreading drinking across at least three days if you drink as much as 14 units a week. Australia has a separate four-standard-drink daily ceiling as well as its weekly guidance. Neither is a target to reach. Alcohol-free days do not create a credit to spend later.
A drink timer can help with pace, but a slower night still needs a total limit. Our guide on how to drink slower covers habits that make the gap between drinks easier to keep. Never use a timer, a weekly limit or a BAC estimate to decide whether you can drive.
A three-question drinking check
AUDIT-C is a short clinical screen built around three things: drinking frequency, the amount on a typical drinking day, and the frequency of heavier occasions. You can start by writing down those same patterns:
- How often? Count the days you drink, including the small midweek ones.
- How much on a typical day? Convert your actual pours to your country's units or standard drinks.
- How often is there a heavier session? Include nights that are unusual but keep happening.
This reflection is not a scored AUDIT-C test. Versions use specific questions, measures and thresholds, so use an official local form with a clinician if you want a screening result. A positive screen is a reason for assessment, not a diagnosis.
When the number isn't the whole story
A total tells you about exposure. It does not tell you whether you can choose when to stop. Signs worth discussing with a doctor include repeatedly drinking beyond your plan, unsuccessful attempts to cut back, strong cravings, and continuing when drinking is hurting work, health or relationships. Needing more to get the same effect matters too.
You do not need to decide whether a label fits before asking for help. Bring a drink log and describe what has changed. A clinician can assess alcohol use disorder and talk through support, including treatment when needed.
When no alcohol is the better answer
General adult guidelines do not apply to every situation. Avoid alcohol during pregnancy and before driving or operating machinery. Check with a clinician or pharmacist if a condition or medicine could interact with it. If you cannot reliably control how much you drink, talk to a professional about whether stopping is the right goal.
Dependence changes how you get there. Shaking, sweating, nausea or a racing heart when alcohol wears off call for medical advice before stopping. Seizures, hallucinations or severe confusion require emergency help. An app cannot assess or manage withdrawal.
What to do with your answer
If there are no dependence concerns, start with an honest record of your normal week. Choose one change you can describe clearly: a smaller pour, a lower-strength drink, or a planned alcohol-free evening. Compare your next week with your starting point rather than with an imaginary perfect week.
You can aim for a lower limit or for zero. Our 12 steps to cut back on drinking turn that choice into a practical plan. If limits keep slipping, add support rather than simply making the promise stricter.
How Pour Decision helps
Pour Decision logs drinks in your country's units or standard drinks, or in grams, so the same week can be compared with the guidance you actually use. Weekly charts make the difference between a quiet week and one heavy evening visible.
If you want to drink less, set custom daily and weekly limits. If your goal is to quit, the app offers a personal plan with weekly goals stepping down to zero. Those are habit tools, not a medical detox plan. Your logs stay on your phone, with no account needed.
Frequently asked questions
How much alcohol is too much in a week?
There is no risk-free weekly amount. The UK's lower-risk guideline is no more than 14 units, Australia recommends no more than 10 standard drinks, and Canada's 2023 CCSA guidance describes 1–2 standard drinks as lower risk. These are different measures of alcohol, not equivalent numbers of glasses.
Is drinking every day a problem?
Daily drinking alone does not diagnose alcohol use disorder. The amount, your ability to stop, and its effects on your life matter too. If you feel shaky, sweaty or sick without a drink, get medical advice before reducing or stopping.
Is a bottle of wine a night too much?
Yes. A 750 ml bottle of 13% wine contains about 77 g of alcohol, or 9.8 UK units and 5.5 US standard drinks. A bottle every night is about 68 UK units a week, far above the UK's 14-unit guideline. Talk to a doctor before making a sharp reduction if this is your usual pattern.
Can I have all my weekly drinks on Saturday?
A weekly guideline is not an allowance to save up. Drinking a lot at once adds short-term risks such as injuries and alcohol poisoning, even if the weekly total looks low.
Does being over a guideline mean I am addicted?
No. Guidelines describe health risk, while alcohol use disorder involves symptoms such as loss of control and continuing despite harm. You can benefit from drinking less without having a diagnosis, and you can need help even when your total is below a guideline.
