Alcohol withdrawal follows a rough clock, not a guarantee. The heavier and longer the drinking, the higher the medical risk.
Call 911 for seizures, severe confusion, or unstable breathing. Call or text 988 for a crisis.
First 6 to 12 hours
Anxiety, insomnia, nausea, sweating, and tremor often begin as blood alcohol falls. People sometimes mistake this for a bad hangover and keep drinking to feel normal.
12 to 48 hours
Symptoms intensify. Hallucinations can appear. Seizure risk rises for dependent drinkers. This is not the window to "tough it out" alone.
48 to 72 hours and beyond
Delirium tremens can emerge with agitation, disorientation, fever, and dangerous vital-sign swings. Even without DTs, sleep and mood problems can linger. Post-acute symptoms are not a reason to skip medical evaluation.
What changes the timeline
Age, liver disease, prior complicated withdrawal, benzo co-use, and poor nutrition raise risk. Kindling means each untreated withdrawal can get worse.

Broker filter
A center that promises a fixed "3-day detox packaged with airfare" without asking about seizure history is selling logistics, not medicine.

Common Questions
How long does alcohol withdrawal last?
Many people feel the worst symptoms in the first 48 to 72 hours. Mild cases settle over several days; complicated withdrawal can last longer and needs medical care.
When do alcohol withdrawal seizures happen?
Seizure risk is highest in the first 48 hours for dependent drinkers, but timing varies. Any seizure needs emergency care.
What are delirium tremens?
DTs are a severe withdrawal state with confusion, hallucinations, and autonomic instability that can be fatal without hospital care.
Can I detox from alcohol at home?
Heavy, long-term drinkers should not quit alone. Medical detox reduces seizure and DTs risk.
