Detox is described as the first step in treatment of alcohol problems because until there is no alcohol in the body, a person cannot participate in the educational and therapeutic process of rehab. But how does it take to detox from alcohol? What’s the timeline.

We review the first hours, days, and weeks of alcohol detox here. And remind you to ALWAYS SEEK MEDICAL SUPERVISION for cases of alcohol dependence. More here on why supervised detox is critical, with a section at the end for your questions about alcohol withdrawal and treatment during alcohol detox.

Alcohol detox duration and length

How long does it take to detox from alcohol? Unfortunately, there is no way to predict alcohol detox duration and length; it is a very individual process. While most cases of acute detox are over within about a week, detox from alcohol can last anywhere from a few hours to several months (especially when complications are present). The alcohol detoxification process is influenced by:

  1. The length of time the individual has been dependent on alcohol
  2. The level of alcohol dependency
  3. The person’s tolerance to alcohol

Additionally, the length and severity of withdrawal symptoms will vary from person to person and depend upon a few factors. The initial symptoms usually are relatively mild and include anxiety, insomnia, and tremors. These symptoms may begin within 3 to 6 hours following cessation of drinking and often before the blood alcohol concentration (BAC) has returned to zero. The symptoms usually abate within 1 to 3 days.  However, what happens when severe alcohol detox symptoms occur?

A schedule for alcohol detox

Alcohol detox begins as the blood alcohol concentration in the central nervous system lowers. Heavy drinkers who abstain from drinking for 5-10 hours will probably get the shakes. Be extremely wary if you get tremors after a few hours of not drinking – it is highly recommended that you seek out a professional detox facility before continuing.

Day 1-2: Symptoms of early alcohol withdrawal may range in severity from mild tremors to massive convulsions. Mild cases of withdrawal can become uncomfortable. Initial symptoms of withdrawal may include headache, tremor, sweating, agitation, anxiety and irritability, nausea and vomiting, heightened sensitivity to light and sound, disorientation, difficulty concentrating, and, in more serious cases, hallucinations. These initial symptoms intensify and then diminish over 24 to 48 hours.

Severe cases of alcohol withdrawal can be life-threatening. Risk of serious complications requires round-the-clock monitoring of blood pressure and vital signs during this time. 6-48 hours after the last drink is the point at which mortality becomes a possible risk. The risk of seizures peaks around 24 hours, and several seizures over several hours are common.

Days 3-4: Two to four days after last use of alcohol, delirium tremens DT’s can occur. This symptom does not occur in most patients, affecting only 5-10% in total. However, the mortality rate for the DT’s is about 15%. This is why its extremely important to detox in a facility equipped to handle detox patients.W hat makes this condition particularly dangerous is the nature of the physiological symptoms. Your body’s central nervous system is hyper-excited, and your circulation and breathing can shift dangerously. You also can experience dehydration that is life-threatening.

Distinctive hallucinations may also occur during withdrawal, usually auditory. These hallucinations may continue for up to two days after they begin, and occur in about 20% of cases of hospitalized alcoholics. They often take the form of accusing or threatening voices. The odds of developing hallucinations increase if you have been using other drugs or you have been an alcoholic for a long time. This symptom relatively uncommon and is generally not dangerous, but it can be extremely unsettling.

Average alcohol detox time

The length of time for someone to make it through alcohol withdrawal and all of its symptoms will vary from person to person. Do not hesitate to seek out medical attention for yourself or prompt a friend to check into a facility for help, especially if a strong dependency has formed. If you notice that someone you know is experiencing severe alcohol withdrawal symptoms, especially delirium tremens, call for medical help immediately.

  3. I am in a situation where I am in medically assisted opiate dependence with suboxone (1 year). 8 months prior, heroin use (snorting), 13 yrs prior Methadone treatment (150mgs), 5yrs prior pharmaceutical opiate addiction which progressed to oxycontin 80mg pills (snorting). Clearly a long extreme opiate/opioid dependence. Consecutive alcohol use and dependence has been an additional, daily problem as well. I am now confronted with the situation of having to STOP MY DRINKING IMMEDIATELY or lose my treatment AND VIOLATE MY PROBATION WITH THE COURT SYSTEM. I am 49 years old and have been drinking 35 years (with exception of approximately 6 yrs due to combined jail time and self willed abstinence). How can I safely but immediately due this given my suboxone treatment??? Your advise would be greatly appreciated. Thank you

  4. I am heavy drinker for5 years have quoted alchoal for last 2 months Iam feeling anxiety now a days should i met a doctor or its age is 30 i don’t have any urge to drink and no physical problem.only Iam constant think negqtive

    1. Hi Deepak. Anxiety can be post acute alcohol withdrawal symptom. Have you tried some herbal and natural meditations to deal with anxiety? Here’s suggested reading on the topic:

      Also, you may speak with a pharamacist to recomend some plant based medication for anxiety. Finally, if nothing works, see a doctor.

  5. My partner has given up alcohol after many years of being a self medicating depressent now 2 months down the track he swears blind he has not had a drink but as in today he sometimes has blurred speech and smells like he has been drinking the day before that stale old man spirit drinker get up in the morning smell is this possible without him having a drink or is he lying to me again.

  6. Is it possible to have dts 4- 7 days after last drink but took over the average dose of advil pm and sominex approx 20 advill and the next day 7 sominex. Would the age of a small female factor in also? She is 80 years old

    1. Hi Susan. Everything can be a factor, from her general health state, to metabolism, level of hydration, the working capacity of her liver and kidneys, as well as her age. I suggest consulting her doctor to be able to get a more accurate response.

  7. Hi Will. Yes; protracted withdrawal symptoms (PAWS) are well documented for long term drinkers and can last for 6-18 months after you stop drinking. Do some more reading about it and talk to a doctor about your symptoms. Main symptoms of PAWS include insomnia, mood disorders, and depression.

  8. Hi I used to drink 6 to 9 beers a day for years I have been sober for six months now cold turkey is it possible to still be having with draw’s ?

  9. Hi Matthew. I can’t say what’s happening and why it is happening. But I believe if you go and see a doctor, he/she can examine your health state and find out what’s causing the nausea. And then, you will have a true diagnosis, rather than just a guess.

  10. I recently finished up my time in the military and have made a number of different lifestyle changes. One of the largest was to shift from what was undoubtedly an unhealthy drinking habit (18+ drinks most nights) to a much more tame one (four or five maybe once a week).

    However I have found that while right after cutting down I was fine starting maybe a few weeks after cutting down I would get very nauseous after only one or two drinks, this has persisted for nearly two months now. It often almost feels like I have to burp, and when I do I feel better for a short time, but it will come right back if I have even one sip of my beer. If I attempt to ignore it and power through I will promptly vomit.

    Like I said I have made other lifestyle changes, my diet is much better, I am smoking more but I don’t want to tackle that until the drinking is handled. Will this fade as my body adjusts? Is there something I can do? Could it indicate another problem?

    Any help would be appreciated, thank you.

  11. Hi Sharon. And thank you for your question. Actually, insomnia is an alcohol withdrawal symptom, a quite common one. Sometimes alcoholics develop what is known as protracted withdrawal. Usually, insomnia starts within 6-12 hours after alcohol cessation. It’s is one the most common symptoms people experiencing protracted withdrawal have to cope with.

I am ready to call
