What may be happening
When you stop or reduce a substance your body has adapted to, you may experience withdrawal. Symptoms can include anxiety, irritability, depression, sweating, tremors, nausea, insomnia, and difficulty concentrating. Timelines differ: alcohol withdrawal often peaks within 24–72 hours; opioid withdrawal frequently peaks within a few days; benzodiazepine withdrawal may require a slow taper over weeks. Severity depends on many individual factors.
What can help
Consult a doctor or addiction treatment program before stopping, especially with alcohol, benzodiazepines, or opioids. Medically supervised detox can provide monitoring, comfort medications, and safer tapering. During detox, prioritize hydration, rest, and following medical advice. Avoid isolating—support from staff, peers, or family can help you get through acute withdrawal. Plan for what comes after detox: therapy, support groups, medication for opioid or alcohol use disorder if appropriate, and relapse prevention strategies.
When to get support
Seek emergency care for seizures, confusion, severe vomiting, chest pain, suicidal thoughts, or signs of overdose. Do not attempt unsupervised withdrawal from alcohol or benzodiazepines if use has been heavy or prolonged. Call or text 988 in the U. S. for emotional crisis support.
