Alcohol withdrawal in a heavy daily drinker ranges from tremor and sweating to seizures and delirium tremens, a state of confusion, hallucination, fever and racing heartbeat that can be fatal, and stopping suddenly is what triggers it. It is a medical emergency in waiting, not a test of willpower: do not force an abrupt stop, do not leave the person alone, learn the warning signs, and obtain medical supervision wherever any exists.
Alcohol withdrawal syndrome is the group of symptoms that follows a sudden fall in alcohol intake in a person whose body has adapted to regular heavy drinking.
Why Stopping Is Dangerous
Alcohol dampens the brain’s activity. With heavy, regular drinking, the brain adapts by damping its own calming signals and boosting its excitatory ones, so that it works normally in the presence of alcohol. When the alcohol is suddenly removed, the brain is left over-excited. The result is tremor, sweating, a racing heart, anxiety and, in severe cases, seizures and delirium (a description of the mechanism recalled from standard pharmacology, not checked for this guide).
The Range Of Severity
- Minor withdrawal: tremor, sweating, nausea, anxiety, poor sleep, a fast pulse, starting within hours of the last drink.
- Hallucinations (seeing, hearing or feeling things) while still aware of the surroundings.
- Seizures, generally appearing earlier than the most severe complication, often within the first couple of days.
- Delirium tremens (DTs): confusion and disorientation, vivid hallucinations, severe agitation, fever, a very fast heartbeat and unstable blood pressure. Typically emerges a few days after the last drink and may come on later in some people.
The timings above are general descriptions from standard medical teaching as I recall it, and they vary between people. The parent guide’s table places the peak of seizure risk at 24 to 72 hours; many references put seizures earlier, with most in the first two days or so. I cannot settle the difference, and the practical point is the same: there is no safe date. Do not stop watching on a fixed day because a table says to. People can deteriorate after seeming to improve.
Who Is At Higher Risk
- Heavy drinkers who drink every day
- Anyone who has had withdrawal seizures or DTs before; each episode may make the next more severe
- People who are ill, injured, dehydrated or malnourished
- Older people
- People also using sedatives
- People who have been drinking continuously for a long time
What the Death Rate Is
Untreated DTs carry a substantial risk of death, and treatment reduces it greatly. The parent guide states a figure of 5 to 15 percent mortality for DTs “even with medical treatment”. I cannot confirm that figure and suspect it overstates the risk with modern care, so I have not repeated it and it has been sent for checking. What is certain is that the risk is serious and falls with medical care.
What Medical Care Does
In a medical setting, benzodiazepines are the standard treatment, vitamin B1 (thiamine) is given, fluids and electrolytes are corrected and the patient is monitored. This guide gives no doses and no reduction schedule: benzodiazepines are themselves dangerous in the wrong amounts and in combination with alcohol, which can suppress breathing, and they are addictive.
If No Medical Care Exists
The immediate danger is abrupt stopping, so:
- Do not create a sudden cut-off. Do not confiscate a dependent drinker’s supply overnight, impose a ban or make someone stop “to see how it goes.”
- Treat reduction as a medical decision, to be made slowly and with the person’s cooperation by the most experienced person available. This guide cannot say how slowly.
- Never leave a withdrawing person alone, and have more than one helper on hand.
- Know the emergency signs: seizure, confusion, hallucinations, fever, a very fast pulse, uncontrollable vomiting. Treat any of these as an emergency.
- Give fluids by mouth to a person who is awake and able to swallow, and offer food they can keep down. Heavy drinkers are often short of vitamin B1, and medical teaching advises that thiamine accompany or precede glucose; sugar water as the only food is not harmless for a malnourished drinker (stated from recollection of medical teaching and not checked). Where any B vitamins exist, seek advice on using them.
- Keep the room quiet, dim and calm with a familiar person present.
- Do not mix sedatives with alcohol.
During A Seizure
Follow the steps in Medical Emergencies: do not restrain, protect the head, do not put anything in the mouth, time it, and place the person in the recovery position afterwards (Recovery Position). A seizure lasting more than five minutes, or repeated seizures without recovery, is a life-threatening emergency.
Delirium
A delirious person may be terrified and may strike out. Use a calm voice and few words, remove hazards, keep two helpers, avoid restraint beyond protecting them and others, and keep them from wandering; see De-escalation.
Common Mistakes
- Cutting off supply as punishment or as a measure.
- Assuming a person who is not shaking is safe.
- Believing that a fixed reduction percentage is safe. The parent guide’s schedule of 10 to 20 percent a day over 7 to 10 days is internally inconsistent: if each cut is a percentage of the starting amount, 20 percent a day reaches zero in about five days, not seven to ten. It is also unsourced.
- Leaving one exhausted helper on watch.
This can kill
Seizures and delirium tremens can cause death. No amateur schedule can make heavy-drinker withdrawal safe. Where medical help exists, take the person to it.
