While people can safely enjoy moderate amounts of alcohol without becoming addicted, those who drink heavily may develop a tolerance for alcohol and eventually become dependent on it. In some cases, heavy alcohol use can lead to a clinical condition called an alcohol use disorder. One symptom of an alcohol use disorder, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), is withdrawal. This happens when a person stops drinking and experiences uncomfortable symptoms such as sleep problems, nausea, and tremors as alcohol leaves the body. In some cases, alcohol withdrawal can lead to seizures, but not everyone who undergoes withdrawal will have a seizure.
