Post-Acute Withdrawal Syndrome, or PAWS, refers to a set of symptoms that can occur after the initial withdrawal phase from substances like alcohol or opioids. Unlike acute withdrawal, which typically lasts a few days, PAWS can persist for weeks or even months. Symptoms may include anxiety, depression, fatigue, and difficulty concentrating, making recovery challenging. The onset of PAWS usually occurs after the acute withdrawal symptoms have subsided. It is believed to result from changes in brain chemistry due to prolonged substance use. Understanding PAWS is crucial for individuals in recovery, as it can help them manage expectations and seek appropriate support.
