What heroin withdrawal feels like
Heroin withdrawal begins 8–12 hours after the last dose. Symptoms include severe muscle aches, abdominal cramping, diarrhea, vomiting, sweating, restless legs, insomnia, anxiety, and overwhelming cravings. Peak intensity is at 36–72 hours; most acute symptoms resolve by day 5–7. Post-acute symptoms (low mood, sleep disruption, anhedonia) can persist for weeks. None of this has to be endured without medication.
