Not knowing what to expect during detox keeps a lot of people from ever starting. The basic shape is simpler than most imagine. You’re evaluated. A medical team watches over you while alcohol or drugs leave your system and treats withdrawal symptoms as they come. Once you’re physically stable, you move into treatment. Most people are surprised it’s more structured, and more humane, than they feared.
It helps to picture each step before you make the call.
What Is Detox?
Detox, short for detoxification, is the stretch of time when your body clears alcohol or drugs and adjusts to working without them. If you’ve become dependent on a substance, that adjustment brings withdrawal symptoms. Medical detox means trained staff manage those symptoms so you’re safe and as comfortable as possible.
Detox treats the physical dependence. It doesn’t treat the addiction itself, and that difference matters more than people expect. Our post on why detox comes before rehab goes into it.
Step 1: The First Phone Call and Intake
It usually starts with a phone call. An admissions counselor will ask what you use, how much and how often, when you last used, whether you’ve had withdrawal problems before, your medical and mental health history, and your insurance. Be as honest as you can. Nobody’s asking so they can judge you; your answers decide how to keep you safe.
Lots of people feel embarrassed on that call. The person on the other end has heard it before, many times over.
Step 2: Medical Evaluation
When you arrive, a medical team does a fuller evaluation. Expect:
- Vital signs: blood pressure, heart rate, temperature
- A physical exam and a review of your medications
- Lab work, often blood tests and a urine drug screen
- Questions about mood, sleep, anxiety and any thoughts of self-harm
- For alcohol, a withdrawal rating with a tool such as the CIWA-Ar scale
With that, the team builds your detox plan: how closely you need to be watched, which symptoms to expect and what medical support you’ll need.
Step 3: Detox and Withdrawal Care
This is the part people worry about most. Withdrawal looks different depending on the substance, how long you’ve used and your overall health.
| Substance | Common withdrawal features | Why supervision matters |
|---|---|---|
| Alcohol | Shakiness, sweating, anxiety, nausea, poor sleep | Can lead to seizures or delirium tremens |
| Benzodiazepines (Xanax, Klonopin, Librium) | Anxiety, insomnia, tremor, agitation | Stopping suddenly can cause seizures |
| Opioids (heroin, fentanyl, pain pills) | Aches, diarrhea, vomiting, chills, intense cravings | Severe discomfort drives relapse; overdose risk rises after tolerance drops |
| Stimulants (cocaine, meth) | Exhaustion, low mood, increased appetite, cravings | Depression can be severe; mental health support matters |
Staff check on you regularly, day and night. They may use medication to ease symptoms, give fluids and nutrition, and help you sleep. You’ll probably feel unwell for part of it. You shouldn’t feel alone or unsafe.
Detox usually takes several days to a week or more, depending on the substance and your health. Your medical team will tell you what to expect in your case.
What a day in detox looks like
Days are simple on purpose. Meals, rest, medical check-ins, a shower, maybe a short walk. As you start feeling better, you might join a group, meet with a counselor or talk with a pastor. Many people sleep a lot at first. That’s normal.
Common worries about detox
Will I be judged? Will my family be told? Can I leave? Those questions come up constantly. Detox staff work with people in withdrawal every day, and their job is to keep you safe, not to lecture you. Privacy laws protect your information, and you decide who’s involved. Ask admissions anything before you arrive. There are no silly questions.
Step 4: Moving Into Treatment
The most important moment in detox is the end of it. Once you’re physically stable, the work on why you drank or used can begin. Going straight from detox into treatment, instead of heading home “to think about it,” gives you the best chance of staying sober. At Covenant Hills, that next step is usually residential treatment, with other levels of care available as you progress.
How to Prepare for Detox
- Ask admissions for their packing list. Most places want comfortable clothes, basic toiletries without alcohol, a list of your medications, your ID and your insurance card.
- Write a few phone numbers on paper in case phone use is limited.
- Line up care for kids, pets and bills ahead of time so you can focus.
- Tell one or two people you trust where you’re going.
- Don’t try to taper or “use up” what you have before you go. Tell the team exactly what you’ve been taking.
For Families
If someone you love is heading into detox, the most helpful things are simple: help with logistics, keep your expectations realistic, and pray for them. They may be irritable, tired or ashamed those first days. That’s withdrawal talking, not the end of the story. As Isaiah 40:31 (KJV) puts it, “they that wait upon the LORD shall renew their strength.”

Frequently Asked Questions
How long does detox take?
Usually several days to a week or more. It depends on the substance, how long and how much you used, and your physical health.
Is detox painful?
Withdrawal can be uncomfortable, but in medical detox, staff use medication and supportive care to ease symptoms and keep you safe.
Can I detox at home?
For alcohol and benzodiazepines, stopping without medical support can be dangerous. With any substance, detoxing at home carries a high risk of relapse. Talk to a medical professional before trying.
What happens after detox?
