What is a common symptom that occurs within 12 hours of alcohol withdrawal?

Tremors are a common symptom that can present within 12 hours of alcohol withdrawal. This symptom typically arises as the body begins to adapt to the absence of alcohol after prolonged use. Alcohol has a depressant effect on the central nervous system, and withdrawal leads to an over-excitation of this system. Tremors often manifest as shaking of the hands but can involve other parts of the body as well. They are usually one of the earliest signs of withdrawal, occurring as the alcohol levels drop and the body's homeostasis is disrupted.

Other symptoms related to alcohol withdrawal, such as seizures, hallucinations, or diaphoresis, may occur as the withdrawal progresses. Seizures, for instance, typically occur between 6 to 48 hours after the last drink. Hallucinations (auditory or visual) can develop within a specific time frame as well, often later in the withdrawal process, while diaphoresis can accompany various withdrawal symptoms but may not be as immediate or specific as tremors. Therefore, the early onset of tremors is a hallmark symptom of alcohol withdrawal during that initial 12-hour period.
