hi.
after the last drink and may include tremors, elevated blood pressure, increased heart rate, and seizures.Alcohol and other drug (AOD) withdrawal also includes changes in mental state (anxiety, depression, and craving) that may outlast the physiological symptoms and motivate renewed AOD consumption.
hope helps uh.

Dependence on alcohol leads to the problem of alcoholism and this often results in the habitual intake of alcohol. The cause of this craving is heavily debated, but the most popular beliefs are that it is a chemical or nutritional imbalance, a genetic predisposition, a neurological effect caused by runaway learning mechanisms or an inability to curb one's own desire for enjoyment. Components Alcoholism is often a controversial subject. Some believe it to be a biological disease, but the inability to tie it to a specific biological causation makes this is a political debate and not a medical one.
Alcohol addiction has been identified as having various components.
Psychological addiction involves those things which convince a person that they gain benefit from the use of the substance. For instance, if they feel that they are more socially adept while drunk or that it allows them to better handle stress, then they might feel that any problems caused were worth the benefits.
Physical addiction (a.k.a., dependence) involves the physical adaptation of a person's biological systems to the continued presence of alcohol in their system. The person's systems become more comfortable when they have the "normal" level of alcohol, and higher doses are required to maintain an equivalent effect. A decrease in the level of alcohol causes reverse imbalances resulting in withdrawal symptoms, which for alcohol can be deadly.
Neurochemical addiction involves the hijacking of existing learning mechanisms in order to convince the system that an addictive behavior is good for it, despite all evidence to the contrary. Endorphin is the body's way of telling the mind that a behavior is good for it. We release endorphin into the blood stream during sex, exercise and consumption of some foods for instance, and this is responsible for "runner's high" and "afterglow". This is more than just a good feeling; it is teaching our brain that these are the behaviors that it should repeat.
It has been demonstrated in various clinical tests that mammals with more active endorphin systems are more prone to alcohol addiction. This is because alcohol triggers the release of endorphins into our system, and we learn that alcohol drinking is a behavior that we should repeat. This effect is also visible in the use of opiates, and in various risk-taking behaviors such as skydiving and gambling. The social problems arising from alcohol abuse often include loss of employment, financial problems, marital conflict and divorce, convictions for crimes such as drunk driving or public disorder, loss of accommodation, and loss of respect from others who may see the problem as self-inflicted and easily avoided.
