Hour-by-hour guide to what happens when you stop drinking, personalized to your drinking level and history.
Alcohol withdrawal can be life-threatening. Severe withdrawal symptoms including seizures and delirium tremens (DTs) can occur within hours of your last drink and require immediate emergency medical care.
This tool is for educational purposes only and does not replace professional medical advice. If you are experiencing withdrawal symptoms, contact a medical professional immediately.
Based on your inputs, you are likely to experience mild withdrawal symptoms. Most people in this range can manage at home with proper support, but always consult a doctor first.
Your drinking pattern and history suggest moderate withdrawal risk. Medical supervision is strongly recommended. Additional symptom cards have been added to your timeline below.
Your risk factors indicate potentially severe withdrawal. Medical detox is strongly advised. Do not attempt to quit without medical supervision. Your timeline includes critical DT risk windows.
A history of severe withdrawal or seizures means you are at high risk for life-threatening withdrawal. Do not attempt to quit without medical supervision.
Ninety-six hours, drawn linear. Every band is as long as the window it names.
Delirium Tremens (DTs) are a medical emergency with a mortality rate up to 37% without treatment.
If the picture above is moderate or severe, the withdrawal risk checker walks the same ground in more detail, and the taper planner covers reducing rather than stopping.
The timeline follows the symptom phases described in the clinical literature on alcohol withdrawal syndrome: early symptoms from roughly 6–12 hours after the last drink, a peak in the 24–72 hour window, alcoholic hallucinosis and withdrawal seizures within the first day or two, and delirium tremens typically between 48 and 96 hours in people at higher risk. These windows are population averages. Your own onset, severity and duration depend on how much and how long you have been drinking, previous withdrawals, other health conditions and medications.

Each time you go through alcohol withdrawal, it can become more severe than the last — a phenomenon neurologists call the "kindling effect." Repeated cycles of heavy drinking and withdrawal cause permanent changes in brain excitability. What was mild shaking the first time can become a full seizure by the third or fourth attempt at quitting. This is why medical professionals strongly recommend supervised detox for anyone with a history of withdrawal symptoms.
Medical detox programs use benzodiazepines and other medications to safely manage the neurological storm that withdrawal creates. Inpatient facilities provide 24/7 monitoring with IV fluids, vital sign checks, and immediate intervention if seizures occur. At-home withdrawal, even for "moderate" drinkers, carries risk — the 24–72 hour window is unpredictable, and symptoms can escalate rapidly without warning. If your timeline shows moderate or severe risk, medical detox is not optional — it is the safest path forward.
If you are going through mild withdrawal with medical guidance, keep these accessible: electrolyte drinks (not sports drinks — look for oral rehydration solutions), B-complex vitamins (especially thiamine, which heavy drinking depletes), easy-to-digest foods like bananas and toast, a thermometer to monitor fever, and the phone number of your doctor or a medical helpline. Avoid caffeine, which can increase anxiety and heart rate. Most importantly, have a trusted person who can check on you every few hours during the first 72 hours.
Every body is different. This timeline represents typical patterns based on medical research, but your experience may vary based on factors including age, body weight, liver health, medications, and genetics. It is not a diagnosis and should never replace consultation with a healthcare provider. If you are considering quitting or reducing your alcohol intake, please speak with a medical professional first.
