Diazepam withdrawal can vary in duration depending on a number of factors, including the individual’s level of dependence and the duration and dosage of their use. Generally, withdrawal symptoms will begin within 1-4 days after the last dose and peak within 7-14 days. However, some symptoms such as anxiety and insomnia can persist for several weeks or even months. It is important to seek medical guidance and support during the withdrawal process, as it can be challenging and potentially dangerous without proper management.
