What Is Withdrawal?

When your body becomes physically dependent on a substance, stopping or reducing use triggers a set of symptoms known as withdrawal. These symptoms occur because your brain and body have adapted to the presence of the substance and need time to rebalance without it.

Withdrawal is not a sign of weakness. It is a medical condition that reflects physiological dependence — and it can be safely managed with proper care.

Withdrawal Timelines by Substance

Opioids (Heroin, Fentanyl, Prescription Painkillers)

• Onset: 6-24 hours after last use
• Peak: 1-3 days
• Duration: 5-10 days for acute symptoms
• Symptoms: Muscle aches, nausea, vomiting, diarrhea, anxiety, insomnia, goosebumps, sweating
• Medical note: Opioid withdrawal is extremely uncomfortable but rarely life-threatening. Medical detox can significantly reduce discomfort

Alcohol

• Onset: 6-12 hours after last drink
• Peak: 24-72 hours
• Duration: 5-7 days for acute symptoms
• Symptoms: Tremors, anxiety, nausea, sweating, increased heart rate, seizures, delirium tremens (DTs)
• Medical note: Alcohol withdrawal can be fatal. Always seek medical supervision

Stimulants (Methamphetamine, Cocaine)

• Onset: Hours to days after last use
• Peak: 3-5 days
• Duration: 1-3 weeks
• Symptoms: Extreme fatigue, depression, increased appetite, vivid dreams, irritability

Post-Acute Withdrawal Syndrome (PAWS)

After acute withdrawal passes, many people experience PAWS — lingering symptoms that can last weeks or months. These include mood swings, anxiety, sleep disturbances, and difficulty concentrating. PAWS is normal, treatable, and temporary.
