Alcohol dependence is a characteristic abnormal behavioral disorder that develops in humans based on chronic excessive alcohol consumption. Large amounts of ethanol enter the body and produce significant clinical toxicity and tissue damage, somatic dependence, and dangerous withdrawal syndromes. A person with alcohol dependence is severely dependent on alcohol, as evidenced by a complete breakdown of the patient’s self-control, while drinking becomes a major activity in his or her life, and the amount of alcohol consumed continues to increase. Alcohol dependence initially manifests itself as excessive drinking, also known as harmful drinking, which is defined as drinking more than 4 standard glasses (equivalent to 2 bottles of beer or 1 tael of 56 proof liquor) of alcohol per day and drinking more than 5 times per week. So, what is the difference between alcohol dependence and general or excessive drinking? Experts usually consider alcohol dependence to be identified in 7 main aspects: 1. Having a compulsive thirst for alcohol. 2. The time interval of abusing alcoholic beverages is determined. 3.The pleasure of drinking alcohol takes precedence over all life activities or work demands. 4.The tolerance of alcohol is increasing and more alcohol needs to be consumed. 5.Drinking alcohol in the early morning on an empty stomach. 6.Insufficient dosage or sudden stopping of drinking will result in various withdrawal symptoms. They are weakness, nausea, insomnia, and tachycardia. 7.After quitting drinking, it is repeated.
