The timeline for opiate withdrawal symptoms can vary depending on the individual and the severity of their addiction, but acute withdrawal symptoms typically peak within 1-3 days after the last use and gradually improve over the course of 5-7 days. However, some people may experience post-acute withdrawal symptoms, which can last for several weeks or months and include issues with mood, sleep, and energy levels. It’s important to note that withdrawal symptoms can be intense and uncomfortable, so it’s recommended to seek medical assistance and support during this time.
