Withdrawal is your brain and body reacting to the sudden absence of a substance they’ve adapted to. What you should do depends on what substance is involved and how severe your symptoms are, but the basics apply across the board: stay hydrated, manage discomfort, reduce stimulation, and know when the situation requires professional help. Some types of withdrawal, particularly from alcohol and benzodiazepines, can be medically dangerous and should not be attempted alone.
Why Withdrawal Happens
When you use a substance repeatedly, your brain adjusts. It reduces the sensitivity of its own receptors to compensate for the drug’s effects, a process called tolerance. Your brain essentially recalibrates its chemistry around the presence of that substance. When you stop, those recalibrated systems are suddenly unbalanced. The discomfort you feel is your nervous system scrambling to function without the chemical it was built around. This is why withdrawal feels like the opposite of the drug’s effects: sedatives cause agitation on withdrawal, stimulants cause fatigue and depression, and painkillers cause heightened pain and sensitivity.
How Long Withdrawal Lasts
Timelines vary by substance, but most acute withdrawal follows a predictable arc. Knowing where you are in the process can help you endure it.
Alcohol withdrawal peaks within 1 to 3 days after your last drink and typically resolves within 5 to 7 days. Opioid withdrawal (from heroin or prescription painkillers) follows a similar timeline, peaking at 1 to 3 days and lasting 5 to 7 days total. Benzodiazepine withdrawal is slower: short-acting versions peak at 2 to 4 days and last about a week, while long-acting benzodiazepines can peak at 4 to 7 days and drag on for two weeks or more.
These are the acute phases. Some people experience lingering symptoms like sleep disruption, low mood, and anxiety for weeks or months afterward. That extended discomfort is real but not dangerous in the way acute withdrawal can be.
Symptoms You Can Expect
Most withdrawal syndromes share a core set of symptoms: anxiety, irritability, insomnia, sweating, nausea, muscle aches, and a racing heart. These are unpleasant but generally manageable for mild cases. The intensity depends on how much you were using, how long you used, and which substance is involved.
Alcohol and benzodiazepine withdrawal stand apart because they can produce seizures, hallucinations, and a dangerous condition called delirium tremens. This is not a risk with opioid withdrawal, which feels terrible but is rarely life-threatening on its own. If you’re withdrawing from alcohol or benzodiazepines, the stakes are meaningfully higher, and medical supervision is strongly recommended.
When Withdrawal Becomes an Emergency
Delirium tremens is the most severe form of alcohol withdrawal and can appear 48 to 72 hours after your last drink. It involves confusion, hallucinations, seizures, dangerously high body temperature, and rapid heart rate. Without treatment, the mortality rate is around 37%. Even with treatment, 5 to 15% of people with delirium tremens die from it.
Seizure risk is highest 24 to 48 hours after the last drink. If you or someone near you experiences confusion, sees or hears things that aren’t there, has a seizure, or develops a very high fever during withdrawal, that is a medical emergency. Call 911 or go to the nearest emergency room.
People with a history of heavy, prolonged alcohol use or previous complicated withdrawals are at the highest risk. If that describes you, do not attempt to quit cold turkey without medical support.
What You Can Do at Home
For mild withdrawal, especially from opioids or stimulants, there are practical steps that make a real difference.
Stay hydrated. Sweating, vomiting, and diarrhea are common during withdrawal and can deplete your fluids quickly. Drink water steadily throughout the day. Drinks with electrolytes (sports drinks, coconut water, or oral rehydration solutions) help replace the sodium, potassium, and magnesium you’re losing. Sip rather than chug if nausea is an issue.
Eat what you can. Your appetite will likely be low, but your body needs fuel to recover. Focus on simple, easy-to-digest foods: broth, bananas, toast, crackers, plain rice. People withdrawing from alcohol are often deficient in B vitamins, particularly thiamine (B1), along with magnesium and folate. A daily multivitamin with minerals is a reasonable starting point, though severe deficiencies from heavy alcohol use typically need medical-grade supplementation.
Control your environment. Withdrawal makes your nervous system hypersensitive. Bright lights, loud sounds, and busy environments amplify your discomfort. Keep your space dim, quiet, and cool. Loose, comfortable clothing helps when your skin feels raw or sensitive. A warm bath or shower can ease muscle aches and general restlessness.
Manage specific symptoms with basics. Over-the-counter pain relievers like ibuprofen or acetaminophen can help with headaches and body aches. Anti-nausea medications available at pharmacies can settle your stomach. Melatonin or chamomile tea may take the edge off insomnia, though sleep will likely remain disrupted for several days regardless.
Coping With the Mental Side
Anxiety, irritability, and cravings are often harder to endure than the physical symptoms. Your brain is temporarily running low on its own feel-good chemicals, which creates a persistent sense of dread and discomfort that can feel unbearable in the moment.
Breathing exercises help more than you might expect. Slow, deliberate breaths (inhaling for four counts, holding for four, exhaling for four) activate your body’s calming response and can interrupt a panic spiral. Grounding techniques work too: focus on five things you can see, four you can hear, three you can touch. These redirect your attention away from the internal chaos.
Remind yourself that the worst of it is temporary. Most acute withdrawal peaks within the first few days and steadily improves from there. When cravings hit, they typically last 15 to 30 minutes before fading. Distraction during that window (a walk, a phone call, a cold shower, even holding ice cubes in your hands) can carry you through.
If you have someone you trust, ask them to stay with you or check in regularly. Withdrawal is easier and safer with another person present, both for emotional support and to recognize warning signs you might miss.
When You Need Professional Help
Some situations call for medical detox rather than riding it out at home. Heavy daily alcohol use, benzodiazepine dependence, a history of withdrawal seizures, or significant underlying health conditions all increase your risk of dangerous complications. Professionals assess your physical health, psychological state, and social support to determine the right level of care, which can range from outpatient check-ins to inpatient medical detox with round-the-clock monitoring.
For opioid withdrawal specifically, there are three FDA-approved medications that reduce symptoms and cravings: buprenorphine, methadone, and naltrexone. Buprenorphine (often combined with naloxone) is the most widely prescribed and can be started during active withdrawal. It partially activates the same receptors opioids target, easing symptoms without producing a full high. Methadone works similarly but requires dispensing through specialized clinics. Naltrexone blocks opioid receptors entirely and is used after withdrawal is complete to prevent relapse.
For alcohol withdrawal, medical teams use sedating medications to prevent seizures and manage agitation. This is not something you can replicate safely on your own, which is why moderate to severe alcohol withdrawal should always involve a healthcare provider.
What Helps After the Acute Phase
Once the worst physical symptoms pass, you’re not done. The weeks and months afterward bring their own challenges: disrupted sleep, low motivation, mood swings, and persistent cravings. Your brain is still recalibrating, and this process takes time.
Structured support makes a measurable difference during this period. Cognitive behavioral approaches help you identify the triggers and thought patterns that lead to use. Behavioral strategies like gradually increasing physical activity, building routine, and reintroducing social connection give your brain healthier sources of the reward signals it’s missing. Support groups, therapy, and continued medication (when appropriate) all reduce the likelihood of relapse.
Physical recovery also continues well past the acute phase. Sleep may take weeks to normalize. Exercise, even just walking, helps regulate mood and rebuild the brain’s natural reward pathways. Consistent nutrition and hydration remain important as your body repairs the damage from prolonged substance use.
