What is a common symptom of alcohol withdrawal?

Tachycardia
Excessive hydration
Hallucinations
Uninterrupted sleep

The correct answer is: Hallucinations

A common symptom of alcohol withdrawal is indeed hallucinations. This phenomenon can occur as the central nervous system undergoes a rebound effect after the abrupt cessation of alcohol intake, which it has become dependent on. During withdrawal, individuals may experience visual, auditory, or tactile hallucinations, indicating heightened arousal in the nervous system due to the sudden absence of alcohol's depressant effects. While tachycardia can also be a symptom of alcohol withdrawal, it is one of many potential physiological reactions and is typically accompanied by other signs such as increased blood pressure and anxiety. Excessive hydration does not generally relate to alcohol withdrawal, as the focus is on managing dehydration and electrolyte imbalances caused by drinking patterns. Uninterrupted sleep is unlikely during withdrawal; individuals are typically restless and may suffer from insomnia due to anxiety or other withdrawal symptoms. Therefore, hallucinations stand out as a distinctive and significant symptom directly related to the neurochemical changes produced by alcohol dependency.
