Which of the following is a common symptom of withdrawal from physical dependence?

• A. Vomiting
• B. Tremors
• C. Insomnia
• D. Hallucinations

Answer: (B)

When someone has become physically dependent on a substance, stopping creates withdrawal symptoms that reflect the body’s rebound to overactive brain and autonomic systems. Tremors are a classic sign because, as inhibitory controls (like GABA) are reduced and excitatory pathways rebound, the nervous system becomes more irritable and the muscles start shaking — especially the hands. This kind of fine, noticeable shaking is common across many types of withdrawal and is often one of the first and most recognizable symptoms. Vomiting, insomnia, and hallucinations can occur with withdrawal too, but they’re less universal. Vomiting depends on the substance and individual factors, insomnia is common but not as distinctive, and hallucinations tend to appear with more severe or specific withdrawals (like alcohol delirium tremens or certain drug withdrawals). So tremors stand out as a broadly typical and early withdrawal sign in physical dependence.
