According to WebMD, cutting out alcohol can include the following benefits:
Reduce your risk of fatalities: The National Highway Safety Traffic Administration states that 32% of all traffic crash fatalities in the United States involve drunk drivers. The National Institute on Alcohol Abuse and Alcoholism adds that 178,000 deaths each year are attributable to excessive alcohol use.
Repair your liver: Heavy drinking can lead to types of liver disease such as cirrhosis (or scarring) of the liver, alcoholic hepatitis and a fatty liver. When you stop drinking, you give the liver the opportunity to repair itself.
Weight loss: If you are trying to lose weight, consider giving up alcohol, which is high in calories and can be high in sugar. When your body is metabolizing alcohol, it also stops metabolizing fat, which can put a halt on weightloss entirely.
Improve your sleep: Drinking large amounts of alcohol before bed can disrupt your sleep and cause poor sleep quality.
Reduce cancer risk: Alcohol is a human carcinogen, according to the U.S. Department of Health and Human Services, which states, “Consumption of alcoholic beverages has been shown to cause cancer of the mouth, pharynx, larynx and esophagus.”
Improve heart health: Drinking alcohol in excess can increase your risk for cardiovascular disease. According to the U.S. Dietary Guidelines, it is recommended that women have one drink or less in a day. As for men, it is recommended that they have two drinks or less in a day.
