🏥 What to expect in your first week of detox ✨

The word "detox" carries a lot of weight, most of it borrowed from films. The reality is more banal and less dramatic. Here's what your first week actually looks like — physically, emotionally, and practically — across the most common settings in Australia.

What detox actually is

Medical detox — clinicians more often call it "withdrawal management" — is a 3- to 10-day medical process. The body adjusts to being without the substance. Symptoms peak somewhere between day 2 and day 4 for most substances, then taper. The role of the clinical team is to keep you safe (some withdrawals are medically dangerous), keep you comfortable (with medications, fluids, and rest), and assess you for the next stage of treatment.

Detox is not "treatment." It's the medical bridge into treatment. People who detox without any plan for what comes next have very high relapse rates — not because detox failed, but because nothing followed it.

Where detox happens in Australia

Hospital detox

For severe alcohol, opioid, or benzodiazepine withdrawal — particularly with a history of seizures, prior delirium tremens, or significant medical comorbidity — detox is done in an acute hospital ward, usually under the care of an addiction medicine specialist or general physician with addiction expertise. You'll have nurses every shift, regular medical reviews, and access to medications including benzodiazepines (for alcohol withdrawal), buprenorphine or methadone (for opioids), and symptomatic medications.

Dedicated detox unit

Many cities have stand-alone detox facilities — sometimes hospital-attached, sometimes free-standing — with 5–25 beds. The medical care is similar to a hospital but the environment is calmer and more recovery-oriented, and the staff are specialists in withdrawal. This is the most common setting for moderately-severe withdrawal in Australia.

Community / home detox

For mild-to-moderate withdrawal, in stable home circumstances, "home detox" or "ambulatory detox" is increasingly common. Your GP and a community AOD nurse provide medications and check in daily. It's lower-cost, lower-disruption, and surprisingly safe for the right person — but requires a stable home, no children present in some programs, and someone to be with you for the first 72 hours.

Private inpatient

Most private residential rehabs offer integrated detox onsite, supervised by a visiting doctor and 24-hour nursing. The medical care is typically equivalent to a public detox unit, with the additional benefit of moving directly into the rehab program without a transfer.

What the first week feels like

The honest answer: rough, then less rough. Specifics depend on the substance.

Alcohol

Day 1 — anxiety, sweating, racing pulse, tremor in the hands. Sleep is broken. Day 2–3 — peak symptoms, often the worst day. Some people hallucinate or have seizures if not properly medicated; this is why supervised detox matters. Day 4–5 — symptoms ease. By day 7 most people feel physically much better, though sleep can stay disturbed for weeks.

Opioids

Day 1 — runny nose, sweating, restlessness, intense cravings. Day 2–3 — peak: severe muscle aches, vomiting, diarrhoea, cramps, restless legs, no sleep. Day 4–6 — symptoms taper. Cravings persist longer than the physical symptoms, often for weeks. Buprenorphine or methadone substantially shortens the acute phase.

Methamphetamine

Day 1–3 — extreme exhaustion, sleeping 16+ hours per day, low mood, anhedonia (nothing feels good). Day 4–7 — energy slowly returns, but mood often crashes. Cravings can be intense and unpredictable. The physical risk is low; the psychological challenge is the dominant one.

Cannabis

Day 1–3 — irritability, insomnia, low appetite, vivid dreams. Day 4–7 — mood instability and cravings, with sleep usually the slowest thing to recover. Withdrawal is real but rarely medically significant.

Benzodiazepines

The most variable and often the longest withdrawal — anxiety, insomnia, sensory disturbances, sometimes seizures. Almost always managed with a slow medical taper rather than abrupt cessation. Detox can take weeks rather than days.

What the staff are doing

A good detox team is doing four things at once: keeping you medically safe, controlling symptoms with the right medications at the right doses, screening for co-occurring conditions you may not have mentioned (anxiety, depression, trauma), and starting to build the plan for what happens after detox. The "treatment" element of detox is mostly assessment and motivation — finding out what's been driving the use, what the person actually wants, and what kind of next-stage program will fit.

Things that surprise people

• Sleep is the slowest thing to come back. Don't be alarmed if you're sleeping badly two weeks in. It often takes 3–4 weeks for sleep architecture to recover, longer for some substances.
• Mood usually gets worse before it gets better. The first 1–2 weeks of being substance-free can feel emotionally flatter than active use, because the brain's reward system hasn't recalibrated yet. This is normal and temporary.
• The "post-acute withdrawal" period is real. Beyond the acute first week, many people have weeks-to-months of low energy, mood swings, and cravings — particularly with methamphetamine, opioids, and long-term benzodiazepines.
• Day 4–7 is often when people walk out. The acute symptoms have eased, the boredom is intense, and the brain starts rationalising ("I feel fine — I don't need this"). This is the moment good detox programs spend the most therapeutic energy on.
• You will think clearer than you have in years. By the end of week one, most people experience a sharpness and emotional honesty that's startling — and often disorienting.

How to make the first week easier

• Accept the medications. Withdrawal medications are not "another drug to be addicted to" — they're short-term tools to keep you safe and functional. Refusing them to "do it the hard way" is one of the most common reasons attempts fail.
• Eat what you can, drink fluids constantly. The body is doing repair work and needs the inputs.
• Don't make any major decisions in the first 14 days. The clarity is real, but the emotional volatility is also real.
• Engage with the therapy. Even when it feels awkward, even when you don't think you "need" it. The relationships you build in the first week are often the difference between staying in treatment and leaving early.
• Tell the staff when something's wrong. Withdrawal symptoms can be controlled; pretending you're fine to be brave just delays the help you could have had.

Detox doesn't fix anything. It makes the actual work of recovery possible — which is the point. By the end of the first week, most people are physically capable of starting therapy, group programs, or whatever comes next. The hard, slow, gradual work begins after detox ends.
