Withdrawal symptoms from diazepam can begin as early as a few hours after the last dose, with the most intense symptoms peaking around days 2-4 and gradually improving over the course of several weeks. However, the duration and severity of withdrawal can vary depending on factors such as the dosage and duration of use, individual differences in metabolism and health, and whether or not the person is tapering off the drug under medical supervision. It’s important to work closely with a doctor when discontinuing diazepam to manage any withdrawal symptoms and ensure a safe and successful recovery.
