How To Taper Off Alcohol


Why Taper?

Some people can just quit drinking alcohol cold turkey without having significant withdrawal symptoms. Other people, however, may suffer significant withdrawal symptoms when they suddenly stop drinking. Alcohol withdrawal is potentially fatal, so if you find yourself starting to experience significant alcohol withdrawal symptoms when you stop drinking then it is important to gradually detoxify from alcohol rather than quitting all at once "cold turkey". You can gradually detoxify from alcohol by tapering off. You can taper off either by using alcohol itself or by using medications.

Some people may also find it easier to just taper off their alcohol use rather than jumping immediately into an abstinence day even if they do not have significant withdrawal symptoms.

Who is likely to have significant alcohol withdrawal symptoms?

What Are Withdrawal Symptoms?

Doctors classify withdrawal symptoms into three categories: mild, moderate, and severe. Even mild or moderate withdrawal can be dangerous for people with high blood pressure or bad hearts. Because withdrawal raises blood pressure there can be a danger of heart attack or stroke.

The longer and harder a person has drunk alcohol--the more severe the withdrawal will be.

Can people successfully use alcohol to taper off?

An unqualified YES. People have been using alcohol to taper off from alcohol since the dawn of history. Withdrawal medications are a recent invention. The idea that tapering cannot be done is a myth created by the alcohol treatment industry.

How do I know if I need to taper off?

If when you stop drinking your hands are visibly shaky, you begin to sweat a lot, you have a rapid or irregular pulse, or your blood pressure is very high then it is advisable to taper off alcohol and not quit cold turkey. You can taper off by using alcohol or by getting prescription meds from your doctor. A pulse of over 100 beats per minute is a definite danger sign.

How do I use alcohol to taper off?

Beer is the best form of alcohol to use when tapering off. If you attempt to taper off using wine or hard liquor you might just wind up getting drunk again because these have higher alcohol content than beer. Try to limit yourself to drinking no more alcohol than necessary when you start tapering. Drink just enough to keep the sweats and shakes at bay. Gradually reduce the consumption of beer as you continue to taper. If the withdrawal is not too extreme you should be tapered off in a day or so. Some people may, however take longer--three days or even a week. If you start to feel withdrawal that is a sign that your taper is not done yet.

It is also very important when tapering off to fight dehydration and to replenish lost vitamins. If you go through a medical detox the people they may rehydrate you with an IV and may also give you vitamin shots. If you are doing a self detox be sure to drink lots and lots of fluids and to take vitamin pills. We recommend Gatorade because it has balanced electrolytes. If you choose to drink water make sure that you get enough salt for electrolyte balance so that you avoid water intoxication.

How much alcohol should I drink when tapering off?

The average person takes around an hour and a half to metabolize a single standard drink--for example one 12 oz beer. People who have a very high tolerance to alcohol can metabolize up to two standard drinks (28 g of alcohol) per hour. People who have a very low tolerance to alcohol might require two or three hours to metabolize a standard drink. Males metabolize alcohol faster than females. The more you weigh the higher your tolerance. Heavy drinkers who have increased tolerance also metabolize alcohol more rapidly than average. On the other hand people who have liver damage and reverse tolerance metabolize alcohol more slowly than others.

Setting Up A Taper Schedule

It is very important that you set up a TAPER SCHEDULE which corresponds to the amount you have been drinking and the amount of withdrawal you might have as a result. The first step in setting up a taper schedule is to estimate your daily baseline consumption of alcohol.

It is very important that you estimate your BASELINE ALCOHOL CONSUMPTION in terms of standard drinks in order for you to be able to set up a taper schedule. You can find the definition of a standard drink here. Just for reference a 12 ounce regular strength (5%) beer is one standard drink. A standard (750 ml) bottle of wine at 12% alcohol contains 5 standard drinks. A 750 ml bottle of 80 proof booze contains 17 standard drinks. A liter of 80 proof booze is 23 standard drinks.

If you have been drinking 20 or more standard drinks a day then we recommend that on the first day of your taper you drink one beer per hour starting when you wake up in the morning for a total of 16 beers the first day. On the second day drink one beer every hour and a half for a total of ten beers. Then continue to taper down by reducing the amounts by two beers per day until you are down to zero.

If your BASELINE ALCOHOL CONSUMPTION is less than 20 drinks per day then we recommend reducing consumption by two standard drinks per day. For example, if you have been drinking an average of 12 drinks per day then your taper schedule can be 10 beers the first day, 8 the second, 6 the third, 4 the fourth, 2 the fifth and 0 the sixth day. Likewise if your average consumption is 6 standard drinks per day you can set a taper schedule of 4, 2, 0.

Some people choose to taper more quickly by cutting the amounts in half--for example 20, 10 5, 2, 0. But if you start having major withdrawal symptoms like bad shakes or pulse over 100 or high blood pressure you are tapering too fast and should slow it down. Monitoring you pulse and blood pressure can be a very good idea while you are tapering especially if you have high blood pressure. If your pulse exceeds 100, your blood pressure goes very high, or you have irregular heart beat then this means that you are tapering too fast and you need more beer.

Only people who are tapering down from very large quantities of alcohol such as a liter of vodka per day will need to start drinking in the morning in order to taper. If you are tapering from smaller quantities and feel no withdrawal symptoms until afternoon or evening then you can wait until then to consume your taper beers. Remember that you are not drinking for pleasure--you are drinking medicine--so only drink what is needed.

Can you stop cold turkey? Many people who have been drinking smaller amounts or for shorter periods may find that they suffer no withdrawal symptoms or only minor withdrawal symptoms and that quitting cold turkey is far easier than tapering.

Always remember that if the taper is not working for you or if you are having major withdrawal that it is safest to check into a medical detox because alcohol withdrawal can kill you.

Can You Taper Too Slowly?

As long as you are progressively reducing the amount you are drinking you are tapering successfully, no matter how long it takes. However, some people find that if they attempt to taper too slowly they wind up rebounding back to baseline levels before they ever reach zero. If you are one of these people then you may want to try to speed your taper as much as you can within the bounds of safety. Many people find that they can finish their taper in two or three days.

How do I taper off with other meds?

If you tell your doctor that you are having a problem with alcohol withdrawal s/he will help you taper off with a benzodiazepine such as Valium or Librium. In some states such as Minnesota the doctor is required by law to commit anyone suffering from alcohol withdrawal to an inpatient detox facility for at least 72 hours. In other states the patient may be allowed to attend and outpatient detox program or the patient may be given a prescription for a benzodiazepine for use for self detox. Typical detox regimens using these medications are as follows: If you do go to a doctor for alcohol withdrawal you may have a diagnosis of alcoholism on your medical records for the rest of your life. This can make it difficult to get medical insurance and sometimes even employment. If you want to avoid this you may choose to do the self-detox using beer as described above.

For reference: 0.5 mg (one half mg) of Xanax is equal to 10 mg valium. 0.5 mg (one half mg) of Klonopin is also equal to 10 mg Valium. (Benzodiazepine Equivalency Table)

Does an instance of alcohol withdrawal mean that I can never safely drink again?

Not necessarily. Every individual must decide for him/herself whether their best option is to pursue a goal of alcohol abstinence, moderate drinking, or harm reduction. If you choose to drink again the best way to avoid another instance of withdrawal is to avoid drinking two days in a row. If you can't do this then at least try to get in three abstinence days during the week. Try to avoid drinking day and night. The more abstinence time you have each week the lower the chance of having another instance of withdrawal. If it is just too damn much work to pursue a goal of harm reduction or moderation with too little payoff, then you may just decide that quitting is simplest. HAMS is wholeheartedly opposed to programs which try to use fear to motivate permanent abstinence from alcohol. We see these programs as usually backfiring and leading people to ever worse binges and ever worse withdrawals. We have found that people are most successful at quitting when they choose that goal for themselves.

What causes alcohol withdrawal?

Alcohol withdrawal is caused by neurotransmitter rebound. The main neurotransmitter system involved in alcohol withdrawal is the GABA (gamma-aminobutyric acid) system. Simply put, GABA receptors cause a person to feel calm, relaxed or sleepy. Alcohol enhances the functioning of these GABA receptors. This is why when people drink alcohol they will feel calm, relaxed, or sleepy. However, when the GABA receptors are exposed to alcohol over a long period of time they struggle to overcome the effect of the alcohol and to return to normal functioning. This is one reason why drinking alcohol has less and less of a payoff when consumed constantly over a long period of time. One is not nearly so relaxed by alcohol the third day into a bender as one was on the first day. After being exposed to alcohol over a long period of time the GABA receptors stop responding as efficiently to the presence of GABA. When the alcohol is suddenly no longer there, these GABA receptors now respond only very weakly to the presence of GABA. The result is anxiety, panic, and insomnia.

Another thing which happens when the function of the GABA receptor is enhanced by alcohol is that the brain tries to overcome this calming effect by producing more adrenaline and other similar neurotransmitters. When the alcohol is completely taken away then this adrenaline and its cousins are left to run rampant in the brain. This leads to raised blood pressure, raised pulse rate, rapid breathing, fever, hallucinations, seizures and D.T.s.

Alcohol also inhibits the glutamate receptor--which is the cause of staggering, slurring, and general interference with muscular coordination. Glutamate receptor rebound also appears to contribute to the withdrawal symptoms described above.

What is "kindling"?

Some people who have repeatedly gone through cold turkey withdrawal without tapering off become more and more likely to have bad withdrawals form even small amounts of alcohol. This phenomenon is referred to as "kindling". People who have undergone kindling can suffer withdrawal seizures from drinking as little as a six pack of beer. Some decades ago some detox facilities forced clients to undergo cold turkey withdrawal to "teach them a lesson". Not only did this fail to stop people from drinking, it resulted in many people suffering from kindling. Fortunately this barbaric practice has been discontinued. The way to avoid kindling is to taper off.

What To Do After You Complete Your Taper

After you complete your taper we recommend that you attempt a period of abstinence from alcohol. Thirty days is a reasonable amount of time to shoot for. This will give your body some time to reset back towards normal and also give you a chance to experience most of the situations where you used to drink without alcohol. Thirty days is just a suggestion; some people may choose a shorter period such as a week and others may opt for something longer such as 90 days. And some people might even find that they like abstinence from alcohol so much that they will opt for permanent abstinence once the trial period is up.
