If it's happening now
Confusion, a fever, a seizure, hallucinations, or a heart rate that won't settle during alcohol withdrawal is a 911 situation, not something to wait out. Maine Crisis Line: 988. For anything short of an emergency, call us at 855-449-7674 and we'll assess it in a few minutes.
Why alcohol withdrawal is different
Heavy drinking over months or years pushes the brain to compensate. Alcohol suppresses the nervous system, so the brain turns the volume up to stay balanced. Remove the alcohol suddenly and that compensation is left running unopposed, the nervous system swings into overdrive. That's the tremor, the racing pulse, the sweating, and in severe cases the seizures and delirium.
Most drugs are miserable to withdraw from. Alcohol and benzodiazepines are the two where withdrawal itself can be fatal. Opioid withdrawal, by comparison, feels worse to many people but is rarely life-threatening, a distinction almost nobody knows before they need to.
The withdrawal timeline
6–12 hours · Early withdrawal
Tremor, sweating, nausea, anxiety, headache, racing heart, trouble sleeping. Uncomfortable but usually not dangerous on its own.
12–24 hours · Escalation
Symptoms intensify. Some people experience alcoholic hallucinosis, seeing or hearing things while otherwise oriented. Blood pressure and pulse climb.
24–48 hours · Seizure window
The highest-risk period for withdrawal seizures, which can occur with no prior seizure history. This is the point where being alone becomes genuinely dangerous.
48–96 hours · Delirium tremens
Severe confusion, agitation, fever, and dangerous swings in heart rate and blood pressure. A medical emergency requiring hospital-level care.
5–7 days + · Resolution and PAWS
Acute symptoms settle. Sleep disruption, anxiety, and low mood can persist for weeks, the stretch where cravings and relapse risk are highest.
Timelines vary. Someone who drinks a bottle of wine most nights may move through this mildly; someone drinking a pint of liquor daily for a decade can hit the seizure window hard. Prior withdrawals matter too, repeated detoxes tend to get worse, not easier, an effect clinicians call kindling.
Who is at real risk
- • Daily or near-daily drinking, especially at high volume
- • Morning shakes, sweats, or nausea that a drink relieves
- • Any past withdrawal seizure or episode of DTs
- • Multiple previous detox attempts
- • Combined alcohol and benzodiazepine or opioid use
- • Liver disease, heart conditions, seizure disorders, or age 60+
- • Poor nutrition or dehydration going into the detox
Why DIY detox goes wrong
The internet is full of home detox advice, and most of it is built on a misunderstanding of what's actually dangerous. Tapering your own drinking sounds reasonable and works for some people, but it fails badly when the plan collides with a bad night. Borrowed benzodiazepines are worse: the dosing is guesswork, the interaction with alcohol suppresses breathing, and you've now added a second dependence. Cleanses, "flushes," and detox drinks do nothing at all for withdrawal physiology.
The other failure mode is quieter. People white-knuckle three days at home, feel awful, drink again to stop the symptoms, and conclude they can't quit. What actually happened is that they tried to do without medication and monitoring what hospitals do with both.
What supervised detox actually looks like
Medically managed alcohol detox is mostly unglamorous and effective: an assessment of your drinking history and health, symptom scoring at regular intervals, benzodiazepines dosed against those scores to prevent seizures, fluids, thiamine and other vitamins to protect against Wernicke's encephalopathy, and monitoring of vitals. Most people are through the acute phase in three to five days and describe it as far less awful than they feared.
Portland Treatment doesn't operate an inpatient detox unit. We coordinate detox with licensed providers we know and trust, matched to your medical picture and insurance, and we stay in contact through it so your treatment starts the day you're out.
The part people skip: what comes next
Detox is stabilization, not treatment. Tolerance drops, the fog lifts, and the underlying reasons for drinking are still there, which is why the first 30 days after detox carry the highest relapse risk of the entire process. The people who do well are the ones who walk out of detox into something already scheduled.
For most people in York and Cumberland County that means stepping into our PHP or intensive outpatient program in Biddeford, often paired with medication for alcohol cravings like naltrexone or acamprosate, then tapering to weekly outpatient care. Our full alcohol rehab program is built around that handoff, and people commute in from Portland, Saco, and Sanford every week.
Not sure whether what you're feeling counts as withdrawal? The warning signs of alcohol addiction are a good place to start, and insurance usually covers more of this than people assume.
Common questions
Can you die from alcohol withdrawal?
Yes. Alcohol is one of only a few substances where withdrawal itself can be fatal. Severe withdrawal can progress to seizures or delirium tremens (DTs), and untreated DTs carry a meaningful mortality rate. With medical supervision and appropriate medication, that risk drops dramatically, which is why we never recommend a heavy drinker quit abruptly on their own.
How long does alcohol withdrawal last?
Symptoms usually begin 6 to 12 hours after the last drink, peak between 24 and 72 hours, and ease over roughly five to seven days. Delirium tremens, when it occurs, typically appears 48 to 96 hours in. Sleep problems, anxiety, and mood swings can linger for weeks, that stretch is often called post-acute withdrawal.
Who needs medically supervised alcohol detox?
Anyone who drinks daily or near-daily, has withdrawal symptoms like shakes or sweats in the morning, has ever had a withdrawal seizure or DTs, drinks heavily and also uses benzodiazepines or opioids, or has significant medical or psychiatric conditions. When in doubt, get assessed, the assessment is free and takes minutes.
Is at-home alcohol detox ever safe?
For light or moderate drinkers with no withdrawal history, sometimes, with medical guidance and someone present. What is never safe is a heavy drinker stopping abruptly alone, or the internet 'protocols' involving tapering with more alcohol, benzodiazepines from a friend, or unproven cleanses. Those approaches miss the exact complications that kill people.
Does Portland Treatment provide detox?
We don't run an on-site detox unit. We coordinate detox with trusted licensed providers matched to your medical situation, stay in contact while you're there, and have your outpatient program ready the day you're discharged, so there's no gap between detox and treatment.
What happens after detox?
Detox clears the alcohol; it doesn't treat the addiction. The relapse risk in the first 30 days after detox is highest for people who go straight home with no plan. Most people step into PHP or IOP immediately, often with naltrexone or acamprosate to reduce cravings, then taper down to weekly outpatient care.
