Why do people overindulge in drinking alcohol? Some people drink too much because they are physically addicted to alcohol, but not everyone who drinks heavily is actually physically dependent on it. A common problem with alcohol use is binge drinking, which is consuming large amounts of alcohol in a short period of time. This is usually about four drinks in two hours for the average woman or five drinks in two hours for the average man. Those who drink heavily at times may end up in a lot of trouble and may make the effort to stop binge drinking, but sooner or later do the same thing again.
