The alcohol withdrawal timeline usually starts 6 to 12 hours after the last drink, with seizure risk highest at 24 to 48 hours and delirium tremens possible from 48 to 72 hours. Most mild symptoms settle within about a week. Enter how long ago your last drink was to see which stage you are likely in and which warning signs to watch for. Withdrawal can be dangerous, so use this checker to understand the timeline, not to replace medical care.

This checker shows typical timing from medical research. Everyone is different, and it cannot diagnose you or tell you that stopping at home is safe. Nothing you enter is saved or sent anywhere.
The alcohol withdrawal timeline checker compares the hours since your last drink with the time windows doctors use to describe withdrawal. It then shows the stage you are most likely in, what that stage usually involves and which stages come next.
The windows come from American Family Physician's 2021 review of alcohol withdrawal and the StatPearls clinical reference on alcohol withdrawal syndrome from the National Library of Medicine. The optional checklist uses risk factors from the same sources. Timing varies with how much and how long you drank, your health and past withdrawals, so treat the result as a guide.
The stages of the alcohol withdrawal timeline are early symptoms, a period when symptoms get stronger, the seizure risk window and the delirium tremens window. Most people only go through the early stages. Seizures, hallucinations and delirium tremens affect a small share of people, but they are the reason withdrawal needs medical support.
| Time since last drink | What can happen |
|---|---|
| 6 to 12 hours | Anxiety, shaky hands, sweating, nausea, headache, insomnia, racing heart |
| 12 to 24 hours | Early symptoms get stronger. Hallucinations are uncommon, affecting about 2% of people |
| 24 to 48 hours | Highest risk of withdrawal seizures |
| 48 to 72 hours | Delirium tremens can begin in about 3% to 5% of people, with symptoms peaking around day 5 |
Sources: American Family Physician, 2021 and StatPearls, 2024. For each stage in more detail, see alcohol withdrawal hour by hour for the first 72 hours, and why alcohol causes shakes and tremors for the most common early symptom.
Alcohol withdrawal is most dangerous from about 24 hours to day 5 after the last drink. Seizures are most likely at 24 to 48 hours, and delirium tremens usually starts at 48 to 72 hours but can appear up to day 8. Signs of delirium tremens include confusion, agitation, visual hallucinations, fever and a fast heartbeat.
StatPearls reports that the death rate from delirium tremens has fallen from as high as 20% to around 1% with modern treatment, and American Family Physician advises inpatient care for anyone who develops it. Learn the early signs in how to recognize delirium tremens, and how doctors lower the risk in preventing seizures in alcohol detox.
People at higher risk of severe alcohol withdrawal include those with past withdrawal seizures or delirium tremens, adults over 65, people with other medical conditions and people who also depend on benzodiazepines. American Family Physician also lists drinking more than 8 drinks a day, active psychiatric conditions and having no caregiver at home as reasons for inpatient care. These are the same risk factors used in the checker above.
If any of them apply, stopping suddenly at home is risky. Our article on when alcohol withdrawal becomes life-threatening explains the warning signs, and the risk of dying from alcohol withdrawal at home covers why supervised detox is safer.
Alcohol withdrawal usually lasts about 5 to 7 days for mild to moderate cases, and American Family Physician notes that symptoms should resolve within 7 days of abstinence. Severe withdrawal and delirium tremens can last longer. For a day-by-day breakdown, read how long alcohol withdrawal lasts.
The alcohol withdrawal timeline follows a fairly predictable pattern. Early symptoms appear within 6 to 12 hours, seizure risk peaks at 24 to 48 hours, and delirium tremens can begin at 48 to 72 hours and appear as late as day 8. Most people only have early symptoms that settle within a week, but risk factors such as past seizures and heavy daily drinking make severe withdrawal more likely. Because the dangerous stages can arrive quickly, withdrawal is safest with medical support, followed by treatment that addresses the drinking itself.

Mild to moderate alcohol withdrawal symptoms usually last about 5 to 7 days. They often start 6 to 12 hours after the last drink and peak around 72 hours. Severe withdrawal and delirium tremens can last longer and need hospital care. Sleep problems and cravings can continue for weeks after the acute phase.
For many people, days 2 and 3 are the hardest, because symptoms tend to peak around 72 hours after the last drink. This is also when the seizure window is closing and the window for delirium tremens is opening. Confusion, hallucinations or a seizure at this point need emergency care.
Alcohol withdrawal is often described in four stages: early symptoms at 6 to 12 hours, stronger symptoms at 12 to 24 hours, the seizure risk window at 24 to 48 hours and the delirium tremens window from 48 to 72 hours. Most people only experience the early stages. Hallucinations, seizures and delirium tremens are uncommon but dangerous.
There is no safe way to speed up alcohol withdrawal, because the timeline depends on how your brain adjusts to the absence of alcohol. The safest approach is medically supervised detox, where staff monitor symptoms and use medication to prevent seizures and delirium tremens. Supervised detox usually takes about a week.
By day 6 without alcohol, mild to moderate withdrawal symptoms are usually easing. Delirium tremens can still appear up to about 8 days after the last drink, so new confusion, agitation or hallucinations at this point are an emergency. Sleep and mood may still feel unsettled while the body adjusts.
