An alcohol addiction is dangerous, and the best way to reduce the risks of drinking is to stop using alcohol. However, quitting cold turkey can be dangerous. Tapering your alcohol intake, or slowly reducing it over time, can help you avoid severe alcohol withdrawal symptoms

You should only attempt an alcohol taper while under a doctor’s care. However, learning more about how an alcohol taper works can help you prepare to quit.

Is Quitting Alcohol Cold Turkey Dangerous?

Quitting alcohol cold turkey can be very dangerous. Although it may seem like the best way to stop alcohol use is to stop drinking right away, this is not the case. Quitting cold turkey can shock your system since it has become used to functioning with alcohol. 

What Happens to Your Body When You Stop Drinking Alcohol?

Heavy drinking causes changes in your brain. In particular, it alters the neurotransmitter gamma-aminobutyric acid (GABA). When you drink a lot over a long period, your brain reduces the amount of GABA it makes. This means that if you quit drinking cold turkey, your brain will not have enough GABA. This can cause your brain to become hyper-excitable and leads to withdrawal symptoms.

Alcohol withdrawal symptoms can include:

  • Sweating
  • Increased heart rate
  • Tremors
  • Anxiety
  • Agitation
  • Seizure
  • Delirium and hallucinations

Withdrawal symptoms often follow a general timeline. For most people, it will look something like this:

  • Six to eight hours after the last drink: Mild withdrawal symptoms like tremor, anxiety and nausea can occur.
  • 12 to 24 hours after the last drink: Hallucinations may start; other symptoms may include tremors, agitation and insomnia.
  • 12 to 48 hours after the last drink: Symptoms may continue to worsen, and seizures may occur.
  • Two to five days after the last drink: Delirium tremens, the most dangerous complication of alcohol withdrawal, can occur. A person may experience symptoms like unstable vitals signs, confusion, agitation, fever, rapid heart rate, high blood pressure and sweating. 
  • One to six months after the last drink: As sobriety is maintained, most withdrawal symptoms will improve. However, lingering anxiety and sleep problems may occur.

Can Tapering or Weaning off Alcohol Reduce Withdrawal Symptoms?

When you slowly taper your alcohol intake over time instead of quitting cold turkey, you reduce the likelihood of withdrawal symptoms. By weaning yourself from drinking, you give your brain the chance to adjust the amount of GABA it produces. 

When you drink heavily, your brain changes the amount of GABA it makes. The imbalance in GABA that occurs when you suddenly stop drinking is what causes withdrawal symptoms. By slowly reducing your drinking over time instead of stopping suddenly, you allow your brain to change its GABA production. 

Strategies for Tapering off Alcohol

There are two main strategies for tapering off alcohol: a direct taper and a substitution taper. Depending on what you drink and how much you drink, you may find that either a direct taper or substitution taper works better to help wean you off alcohol:

  • Direct taper: In a direct taper, you continue to drink your regular drink but slowly decrease the amount over time. Direct tapers work best for drinks that contain a low percentage of alcohol, such as beer.
  • Substitution taper: In a substitution taper, you switch your regular drink to a different one. For example, if your regular drink is a strong liquor, a substitution taper would involve counting up your daily drinks and then switching to an alternative that contains less alcohol, like beer. You would then slowly reduce the amount of beer that you drank over time.

Some drinks, such as liquor or spirits, contain a high percentage of alcohol. If your typical drink contains a high alcohol percentage, a substitution taper may be safer than a direct taper for several reasons:

  • It can be easier to measure your intake of beer versus spirits.
  • It can be harder to binge drink beer versus spirits.
  • Because beer contains more water than spirits, it is easier to remain hydrated.
  • It can be easier to adapt your body to drinking smaller amounts of alcohol with a substitution taper.

However, it’s important to note that people with moderate to severe alcohol addictions may struggle with sticking to a taper schedule and end up relapsing to heavier alcohol use. In these cases, a medical detox may be the best option.

How Long Does It Take to Taper off Alcohol?

It can take different people varying amounts of time to taper off alcohol. How long it takes depends on factors like how much you typically drink. A person who drinks more alcohol will probably have a longer taper than a person who drinks less alcohol.

Another big factor in how long a taper lasts is alcohol withdrawal symptoms. After all, the point of a taper is to avoid alcohol withdrawal. If you begin to have withdrawal symptoms during your taper, this is a sign that your taper may be going too fast and that you need to slow it down. Doing so can prolong the duration of your taper.

Alcohol Taper Schedule

Addiction experts have not conducted many studies on alcohol tapering. As a result, little information is available regarding the best way to taper. That said, some independent groups have stepped in, publishing sample tapering schedules to guide people who are trying to cut back on drinking. 

The sample schedules state that if you drink fewer than 20 standard drinks a day before starting the taper, you should reduce your alcohol intake by two drinks a day until you get to zero drinks. The schedule becomes a little more complex if you drink more than that. If you drink 20 or more standard drinks a day before starting the taper:

  • Day one: Drink one drink each hour for a total of 16 drinks.
  • Day two: Drink one drink each hour and a half for a total of 10 drinks.
  • Days three through seven: Reduce your drinking by two drinks each day until you get to zero drinks

Because tapering can be tricky and alcohol withdrawal syndrome can be dangerous, you should never start a taper before talking to your doctor. 

Challenges of Quitting Alcohol

Quitting alcohol can be hard, and not just because of the withdrawal symptoms. Knowing ahead of time that quitting may be difficult can help you plan the best way to address these challenges. In turn, this increases both your confidence and your chances of success. Common challenges include:

  • Losing a coping strategy: Many people drink alcohol to cope with mood problems like anxiety, depression and stress. When you stop drinking, you will need to find a different coping strategy for these problems. Fortunately, this is exactly what rehab programs train you to do after you quit drinking.
  • Avoiding triggers: When you drink on a regular basis, you likely have certain rituals for when you drink. For example, you may drink every time you see your friends or at night before going to bed. These situations can serve as triggers for you, and they may lead to alcohol cravings because you are used to drinking at those times. Learning how to avoid triggers is an important part of maintaining your recovery.
  • Finding supportive relationships: If you spend a lot of time with people who drink heavily, your new sober lifestyle may be harder to maintain. Finding new relationships that support your sobriety is important.
  • Dealing with relapses: Relapses are common, but they are not the end of the road. Learning how to reduce the chances of a relapse and knowing how to move forward with your sobriety despite a relapse are important parts of the recovery process.

The Benefit of Medical Detox for Tapering off Alcohol

Because alcohol withdrawal symptoms can be life-threatening in some cases, safety is crucial when you work towards sobriety. Little scientific evidence exists regarding tapers, but medical detox has been proven to be a safe and effectiveway to quit drinking. 

In medical detox, doctors and nurses provide around-the-clock care while helping you wean off alcohol. Medical detox is then followed by inpatient and outpatient rehab to help you maintain your sobriety over the long term, and medication-assisted treatment may be prescribed as medically appropriate.
