Introduction
Withdrawal symptoms typically last for 1–2 weeks, with most people experiencing the most intense symptoms within the first week, followed by gradual improvement. In a few cases, symptoms may persist for 1–3 months or even longer. The severity of symptoms and recovery speed vary from person to person, so appropriate scientific management is essential. If severe vomiting, high fever, confusion, or similar conditions occur, prompt medical attention is recommended.

Withdrawal symptoms typically last for 1–2 weeks, with most people experiencing the most intense symptoms within the first week, after which they gradually subside. In a few cases, symptoms may persist for 1–3 months or even longer. The severity and recovery speed vary from person to person, so it's important to respond appropriately and scientifically. If severe vomiting, high fever, confusion, or similar conditions occur, prompt medical attention is recommended.

The duration of withdrawal primarily depends on the type of substance or behavior being discontinued. For commonly addictive substances such as alcohol and nicotine, withdrawal symptoms usually peak within 1–2 weeks. However, for benzodiazepines or opioids, the withdrawal period may be longer, and some individuals may experience protracted symptoms.

An individual’s physical condition and degree of addiction also influence the duration. People who have been addicted for a shorter time, used lower doses, and have good baseline health generally experience shorter withdrawal periods. In contrast, those with long-term, heavy addiction or underlying medical conditions may suffer more severe and prolonged symptoms, requiring a gradual, step-by-step approach to cessation.

During withdrawal, ensure adequate sleep and a balanced diet, avoid exposure to triggers associated with the addiction, engage in mild physical activities such as walking, maintain emotional stability, and support your body's recovery through regular routines and a positive mindset.
