Which of the following is NOT a typical sign of withdrawal symptoms?

In the context of withdrawal symptoms, increased energy is not typically associated with the withdrawal process. Withdrawal symptoms generally manifest as the body reacts to the absence of a substance that it has become dependent on. Common signs of withdrawal include physical and psychological symptoms that reflect the body's struggle to regain its equilibrium.

Craving, pain sensitivity, and nausea are all well-documented symptoms that individuals may experience during withdrawal. Craving reflects a strong desire to consume the substance to alleviate the discomfort of withdrawal. Pain sensitivity can increase as the body becomes more reactive, and nausea is a common gastrointestinal symptom during withdrawal.

In contrast, withdrawal symptoms usually lead to fatigue, lethargy, or decreased energy levels, as the body is undergoing stress and adjustment. Therefore, increased energy stands out as an atypical response during withdrawal, making it the correct answer in identifying which option does not align with expected withdrawal symptoms.
