Symptoms of an alcohol problem include personality changes, blackouts, drinking more and more for the same "high," and denial of the problem. A person with an alcohol problem may gulp or sneak drinks, drink alone or early in the morning, and suffer from the shakes. He or she may also have family, school, or work problems or get in trouble with the law because of drinking.
The use of alcohol with medications or illegal drugs may increase the effects of each. Alcohol abuse patterns vary. Some people get drunk every day; others drink large amounts of alcohol at specific times, such as on the weekend. It is common for someone with an alcohol or drug problem to call in sick for work on Monday or Friday. He or she may complain of having a virus or the flu. Others may be sober for long periods and then go on a drinking binge that lasts for weeks or months.
Someone with alcohol dependency may suffer serious withdrawal symptoms, such as trembling, delusions, hallucinations, and sweating, if he or she stops drinking suddenly ("cold turkey"). Once alcohol dependency develops, it becomes very difficult to stop drinking without outside help. Medical detoxification may be needed.
