Alcohol withdrawal symptoms

The shaky, sweaty, can’t-think part of stopping is where most people get scared, and where most of the bad information lives. So here’s what’s actually known, said plainly.

The short answer

Most alcohol withdrawal symptoms are unpleasant but expected: anxiety, shakiness, sweating, headache, nausea, trouble sleeping, vivid dreams. A smaller group are warning signs: seizures, severe confusion, hallucinations, fever. Symptoms tend to start within 8 hours of the last drink (but can appear days later) and peak by 24 to 72 hours (MedlinePlus). Most last 3 to 7 days, and the NHS agrees.

Symptoms, sorted by how much to worry

Everything below comes from MedlinePlus, the NHS and StatPearls. None of them rank the symptoms, so the sorting is mine, based on which ones they tie to emergencies.

Symptom	Where it usually sits	What to do
Anxiety, nervousness, jumpiness	Common	Slow breathing, dim room, tell someone
Shaky hands or body (tremor)	Common. Severe shaking is a warning sign	Eat something, sit down, don’t drive
Sweating, clammy skin, pale skin	Common	Fluids, cool the room
Headache	Common	Water, rest
Nausea, loss of appetite, some vomiting	Common. Vomiting you can’t stop is a warning sign	Sip fluids, bland food in small amounts
Insomnia, nightmares, vivid dreams	Common	Lie down in the dark anyway, no pressure to sleep
Fatigue	Common	Rest
Irritability, mood swings, low mood	Common	Tell the people around you what’s happening
Not thinking clearly	Common. Sudden severe confusion is an emergency	Keep a person close
Rapid heart rate	Common. An irregular heartbeat is an emergency	Sit, breathe slowly, watch it
Enlarged pupils	Listed by MedlinePlus	Nothing to do
Fever	Emergency	Call for help
Hallucinations	Emergency	Call for help
Seizure	Emergency	Call for help

The severe symptoms

Delirium tremens is “a severe form of alcohol withdrawal” (MedlinePlus). It brings agitation, sudden severe confusion (delirium), fever, hallucinations and seizures. Death is possible, especially if delirium tremens occurs, and that’s MedlinePlus saying it, not me being dramatic. Seizures most often come between 8 and 48 hours after the last drink, and delirium tremens typically shows up around 3 to 5 days in, sometimes later (StatPearls).

Two things I want to say plainly:

• Most people don’t get these. I couldn’t find a reliable personal risk number, and I won’t invent one.
• If you might be one of the people who does, the time to know is before you stop.

What helps with the mild symptoms

These are plain comforts, not treatment. They don’t make severe symptoms safe.

• Eat small and often. Toast, eggs, soup, rice, fruit. Appetite may be gone, so eat anyway.
• Keep fluids going. Sweating and vomiting drain you.
• Make the room easy. Dim, cool, quiet. A fan or a blanket, whichever you need.
• Breathe slowly. Longer out than in. The Slow things down tool in Ease times it for you.
• Lie down even if you can’t sleep. Rest still counts.
• Have a person check in. A text morning and evening for the first three days.
• Don’t add sedatives or leftover pills. Mixing them with withdrawal can be dangerous.
• Don’t drive if you’re shaky, dizzy or foggy.

The symptoms that linger

When the first week is over, a few symptoms don’t leave with it. Symptoms may go on for weeks, and some, including sleep changes, rapid changes in mood and fatigue, may last for months (MedlinePlus). That’s a “may,” not a “will,” and it varies a lot. If it’s you, you’re not doing it wrong.

A plain, repeated day helps more than any trick. Today is built for that, and Ease shows how steady your wake-up time is getting, which is one of the quiet signs things are settling.

Is it withdrawal or something else?

I can only tell you what’s known about withdrawal itself. It’s a set of symptoms that begins after you cut down or stop and follows the timing above. If symptoms start long after your last drink, or get steadily worse after the first couple of days, treat that as a warning sign and get urgent help.

What to do next

• If you haven’t stopped yet, check whether stopping suddenly is safe for you before you stop.
• If you’re in the middle of it, use the table above, set up your space, and keep someone close.
• If you’re past the first week, what happens when you stop drinking covers months two to twelve.
