An increasing tolerance to the effects of alcohol. You may have heard the expression that someone can “hold their liquor.” This is not a sign that this person will not have problems with alcohol; in fact, this may be an early sign of alcoholism as a disease.
A growing preoccupation with or interest in drinking. Also drinking alone or drinking before an activity where there will be drinking. It may seem as though one simply enjoys drinking. We now know that these can be part of the definition of alcoholism.
A person will dispute their drinking is a problem. This symptom, called denial, is almost always present in the disease of alcoholism. Later, difficulties in relationships, on the job, or with the law often occur.
Other signs and symptoms closely matching the definition of alcoholism are:
Hiding alcohol or sneaking drinks
Gulping the first few drinks
Wanting to drink more, or longer, than the rest of the crowd
Losing control of drinking, leading to attempts to control it (“going on the wagon”)
