Dependence on alcohol

Often, people drink to try and reduce symptoms of underlying emotional or psychological disorders (also known as self-medicating). But in the long term, alcohol makes these disorders worse because it interferes with the chemical balance in our brains.

What happens to cause alcohol dependence and how can it be treated? We review here. Then, we invite your questions about physical dependence on alcohol at the end.

Alcohol dependence vs. alcohol abuse

Alcohol dependence and alcohol abuse are two types of problem drinking. But these two conditions manifest specific symptoms and require different types of treatment. So what are the differences between abusing alcohol and being dependent on alcohol?

Alcohol abuse occurs when a person drinks too much and too often but is not physically dependent on alcohol. In addition to its physical effects, this abuse can lead to dangerous behavior such as driving a car after drinking, or to legal problems such as an arrest for drunk driving. Alcohol abuse can also involve trouble with personal relationships and with taking care of home or work responsibilities. People who abuse alcohol often continue to drink, even though they know it may cause these problems.

Alcohol dependence is diagnosed when, upon slowing down or stopping drinking, a person experiences withdrawal symptoms. When they stop drinking, an alcohol dependent person can get nauseated, sweaty, shaky, and restless. These withdrawal symptoms cause them to start drinking again, even though doing so can lead to physical or mental problems. This is why alcohol dependence is considered a more serious problem than alcohol abuse. It is an indication of the presence of alcoholism, a lifelong disease in which people have a strong need to drink, cannot control their drinking once they start, and need to drink greater amounts of alcohol over time.

Alcohol dependence time: How long to be dependent on alcohol?

When you’re drinking on most days, you can become psychologically dependent on alcohol. Breaking your drinking cycle is an important way to test for and tackle dependence on alcohol. Try taking some days off from drinking. It can prevent your body from becoming accustomed to alcohol and help to lower or reset your tolerance.

If you drink regularly, your body builds up a tolerance to alcohol. Tolerance is a physiological response we have to any drug: the more you consume, the more your body needs to have the same effect. Regular drinking induces certain enzymes in your liver that break up (metabolize) alcohol. If you drink heavily over weeks or months, levels of these enzymes go up, your tolerance builds and you need more alcohol to get the same effects.

Brain systems get tolerant to alcohol too, and although you may be able to walk a straight line after drinking quite a lot, this means the brain has adapted so that next day the brain cells expect alcohol. Keep in mind that it is never advised that you go cold turkey off alcohol if you’ve become dependent on it.

Dependence on alcohol symptoms

  1. Illnesses from alcohol use, such as alcoholic liver disease
  2. Needing more and more alcohol to feel drunk
  3. The presence of alcohol withdrawal symptoms when you haven’t had a drink for a while

The primary symptom of dependence on alcohol is a set of “withdrawal” symptoms that occur when you slow down or stop drinking completely. Alcohol withdrawal symptoms usually occur within 8 hours after the last drink, but can occur days later. Symptoms of alcohol withdrawal usually peak in 24 – 72 hours after your last drink, but may persist for weeks. Common symptoms of alcohol withdrawal include:

  • anxiety or nervousness
  • confusion
  • depression
  • fatigue
  • irritability
  • jumpiness or shakiness
  • mood swings
  • nightmares
  • not thinking clearly
  • sweating
  • tremor of the hands or other body parts

Other symptoms which occur during alcohol withdrawal can include: clammy skin; enlarged (dilated) pupils; headache; insomnia (sleeping difficulty); loss of appetite; nausea and vomiting; pallor; and rapid heart rate. A severe form of alcohol withdrawal called delirium tremens can cause more severe symptoms that require medical treatment including seeing or feeling things that aren’t there (hallucinations) and/or seizures.

Physical dependence on alcohol

Physical dependence on alcohol occurs when a person’s body has adapted to chronic drinking, and manifests as physical symptoms when s/he stopped drinking. NOTE: A person can be psychologically dependent on alcohol without being physically dependent, but a person can’t be physically dependent without being psychologically dependent. Chronic alcoholism occurs when physical and psychological symptoms of dependence are present. Alcoholism is treatable and controllable, but not curable.

Psychological dependence on alcohol

Psychological dependence on alcohol include drinking in order to function “normally” and feel good. If you use alcohol to try and improve your mood, you may be starting a vicious cycle. Anxiety, depression and suicidal feelings can all develop when you’re psychologically dependent on alcohol. This is because regular, heavy drinking interferes with neurotransmitters in our brains that are needed for good mental health.

Being dependent on alcohol can also affect your relationships with your partner, family and friends. It might mean you don’t perform well at work and if that continues for any length of time you could face losing your job, leading to financial problems as well. If you think your mental health is suffering because of your drinking, but you feel you’re not able to stop, ask for professional help. Non-judgmental assistance is available all over the country.

Alcohol dependence withdrawal

If you suspect that you are dependent on alcohol, never try to quit drinking cold turkey. Always seek medical assistance. Permanent and life-long abstinence from alcohol is the best treatment for those who have gone through withdrawal. It is important that after alcohol dependence withdrawal a person goes home to a living situation that helps support them in staying sober. Some areas have housing options that provide a supportive environment for those trying to stay sober.

Moderate to severe alcohol dependence withdrawal

People with moderate-to-severe alcohol detox symptoms may need inpatient treatment at a hospital or other facility that treats alcohol withdrawal. You will be watched closely for hallucinations and other signs of delirium tremens. Treatments for alcohol dependence and withdrawal may include:

  1. Administration of anti-seizure or anti-psychotic medications if necessary
  2. Monitoring of blood pressure, body temperature, heart rate, and blood levels of different chemicals in the body
  3. Fluids or medications through a vein (by IV)
  4. Sedation using medication called benzodiazepines until withdrawal is complete

Mild to moderate alcohol dependence withdrawal

If you are experiencing mild-to-moderate alcohol withdrawal symptoms, you can often be treated in an outpatient setting. You will need someone to commit to staying with you during this process and who can keep an eye on you. Daily visits to your health care provider are often needed until you are stable. Treatment for mild alcohol dependence usually includes:

  1. Blood tests
  2. Patient and family counseling to discuss the long-term issue of alcoholism
  3. Sedative drugs or drugs which address cravings for alcohol to help ease withdrawal symptoms
  4. Testing and treatment for other medical problems linked to alcohol use

Is it really so terrible to enjoy getting drunk? I mean, I avoided it for years, always under the impression that it was a “bad” thing, and obviously alcoholism in the extreme is a terrible disease that can negatively affect people’s lives – I don’t discount that at all. However, just recently I started drinking a bit, and got quite pleasantly drunk, and I really liked the feeling…a lot. Nothing bad happened. I just had a few (OK, maybe quite a few) drinks until I felt quite “happy”; watched TV and staggered around my apartment for a bit while enjoying the feeling; and then went to bed. The next morning, sure, I felt a little lethargic and my thinking was a little fuzzy for a bit, but otherwise, all back to normal. So now I have done this on and off for several months. I don’t go out and drink; I just enjoy the experience at home. I’m very careful not to drink so much that I end up “falling-down, throwing-up drunk” but I do drink enough to get to that lovely woozy pleasant feeling. Once in a while I might do this several nights in a row (depending on whatever’s going on in the rest of my life), but more often it’s hit and miss, here and there.

So, must I really be all that worried about this? I’m not drunk 24/7 and frankly, no one ever sees me drunk. I’ve just found it to be a very pleasurable activity that I do (mostly) now and then. Is that really so bad?

My friend has been drinking heavily for over 30 years. He is now 76 years old. His doctor told him he needed to detox from alcohol and he agreed. He went into or under the detox drug Atavan on October 6, 2014 and was gradually tapered off it the following week. He was in a very poor mental state after being tapered off the Atavan. My friend wanted to get out of bed and get out of the hospital because he was obviously going stir crazy in the hospital room. We are now approaching one month after he entered alcohol detox. He is in his home but he has a major case of insomnia (never, ever, sleeps at night and sleeps only 20 min in the mid morning) this has been going on since they doctor tapered him off the detox drugs!! Will my friend recover? Will it just take him some time and patience?

Hi Tricia. It sounds like you are describing some of the “post acute withdrawal symptoms” (PAWS) that can accompany heavy drinking. Do some reading on PAWS for alcohol withdrawal and inform your friend (and his doctors) about these symptoms…keeping a calendar record of the symptoms can help!

Hello,

I was wondering if one were to no longer become physically dependent on alcohol after going through withdraw from a severe addiction, can they have a drink or two socially while being monitored? Or will this cause the person to endure the exact same symptoms of withdrawal that they did when drinking everyday heavily for months? Even if absolutely no symptoms have surfaced for months?
