In short

The first days come first. If your body is dependent on alcohol, stopping suddenly can be very dangerous (NHS), and withdrawal begins within 6 to 12 hours of the last drink. Message us before you stop and we tell you whether you need a medical detox.
The body then gives some things back, on different clocks. In one UK study of drinkers without dependence, the liver enzyme GGT fell by 28.6% in a month. Fatty liver can recover over months or years. The risk of mouth and oesophageal cancers falls over years.
Some promises have nothing behind them. No guideline gives a day for clearer skin or a date for the immune system to recover.
Renewed Life Center in Lakeside, Cape Town, runs medical detox with 24-hour nursing supervision. Admission can be immediate and usually happens within three days of first contact.

Most people who type this question are standing at one of two doors. Some drink most evenings and wonder whether a dry month would be worth it. Others drink every day and want to know what the first week will do to them. The answer is different for each of them, and some of the popular claims have no evidence behind them at all.

What happens in the first days after your last drink?

If your body is dependent on alcohol, the first days bring withdrawal, not benefits. Symptoms begin within 6 to 12 hours of your last drink and usually last from 3 to 7 days (NHS), and stopping suddenly can be very dangerous in that case. Message us before you stop and we tell you whether you need a detox.

The hour-by-hour picture belongs on our alcohol withdrawal timeline, and how to stop without hurting yourself is in how to stop drinking alcohol safely. If you drink most days, message us before you stop, even if you have never had withdrawal symptoms. If you drink less, the changes below start from your first dry days.

Anyone who is dependent needs medical help through those days. At Renewed Life Center detox begins with a risk assessment before withdrawal starts. Nurses supervise around the clock, our resident GP carries out the medical assessment, and medication is used only when it is clinically indicated and prescribed by a medical professional.

Call for an ambulance now if, after stopping, someone is having a seizure; or confused, or seeing and hearing things that are not there. In Cape Town, the Western Cape Government lists 10177 for an ambulance and 112 from a mobile phone.

Will you sleep better after you stop?

Often, but not overnight, and not straight away if you were dependent. The NHS lists better mood, memory and quality of sleep among the benefits of cutting down. A review of people with alcohol use disorder found only limited recovery of sleep disturbances within the first 30 days of abstinence.

The same review says some people who stay abstinent for a long time still have persistent sleep problems. Poor sleep in the first weeks after stopping is common. If it drags on, tell us and it goes into the assessment.

What helps is dull and works: a fixed bedtime, a dark room, no screen for the last half hour, and no coffee after lunch. The evening itself, the hour the first drink used to arrive, is covered in the guide to stopping safely.

What happens to your liver, and can fatty liver recover?

Fatty liver can recover, but the timescale is months or years, not days. The NHS says the liver can usually recover if you stop drinking, and Liver UK says the damage from alcohol-related fatty liver may be reversed if you stop for a period of time (months or years).

Fatty liver is the early stage. Both sources speak about that stage. Anything more advanced is for the medical assessment with our resident GP.

You may hear about GGT, a liver enzyme measured in a routine blood test. In a UK study of moderate to heavy drinkers without dependence or liver disease, GGT fell by 28.6% after one month without alcohol. That is the result of one study in one kind of drinker. It shows the direction of travel and gives no date for anyone else. If you drink heavily, get a liver blood test before you stop and another a few months on, so you can see your own numbers.

Does your blood pressure come down?

If you were drinking a lot, yes. A review of 36 trials found that people who drank more than two drinks a day and cut back lowered their blood pressure, while for people drinking two or fewer a reduction was not associated with a significant fall.

The biggest effect in that review, published in The Lancet Public Health in 2017, was among people who drank six or more drinks a day and cut their intake by about half: systolic pressure fell by 5.50 mm Hg and diastolic by 3.97. That was cutting down, not stopping. In the UK study above, systolic pressure fell by 6.6% and diastolic by 6.3% after a month without alcohol.

The trials count a “drink” by their own measure, which is not the same everywhere, so count what you actually pour in grams, not glasses. And have your blood pressure checked before and after: you will know it has changed only if you measured it.

Will you lose weight, and how many calories does it save?

Probably some, because alcohol is calorie-dense. The NHS says a standard glass of wine can contain up to 158 calories, and some pints of stronger lager up to 222. Alcohol itself carries 7 calories per gram, almost as many as a gram of fat.

In the UK study, weight fell by a median of 1.5% after one month without alcohol. Some people swap the wine for sugary drinks or late-night food, and the scales do not move.

Will anxiety and low mood improve?

If you were dependent, anxiety and low mood often ease within weeks. A review of studies of people with alcohol use disorder found that clinical depression and anxiety symptoms dropped to a normal range after 2-4 weeks of abstinence. The same review cautions against diagnosing a separate depression or anxiety disorder in the first few weeks.

If your anxiety or low mood is no better after that stretch, it may be a condition of its own that the drinking was covering. That is treatable, and it is a different job from stopping drinking.

It is the job of the psychological side. Dr Ruby Weber heads psychology at the centre, with over two decades in the addictions field working with international and South African clients. Where anxiety, depression or trauma sit under the drinking, we treat them on the same plan, in one place, and a psychiatrist selects medication where it is needed. Medicines that turn down cravings are compared in medication for alcoholism. See why treating addiction and mental health together matters.

Anxious since you stopped, or before you started? Tell us about it on a free call. We reply the same day.

Does quitting lower your cancer risk, and what about immunity?

The risk of some cancers falls, slowly, over years. The US National Cancer Institute says stopping is associated with lower risks of oral cavity and oesophageal cancers and possibly of throat, breast and colorectal cancers, and that it may take years to reach the risk of people who never drank. The World Health Organization calls alcohol an established carcinogen.

For immunity there is no timetable. The US National Institute on Alcohol Abuse and Alcoholism (NIAAA) says drinking too much can weaken the immune system. It gives no date for recovery, so a claim that your immune system is back to normal after 30 days has nothing behind it.

What changes over the weeks, months and years, and what has no evidence?

Measured changes run from hours to years: withdrawal starts within hours, mood and liver blood tests shift within weeks, fatty liver recovers over months or years, and cancer risk falls over years. The table shows how firm each one is. Most come from a single review or study, and they describe groups of people, not you.

What has been measured after stopping or cutting down
When	What changes	How firm
Hours and days	Withdrawal in people who are dependent: 6 to 12 hours to start, usually 3 to 7 days	NHS guidance
2 to 4 weeks	In people with alcohol use disorder, depression and anxiety symptoms dropped to a normal range	Review of studies
About 1 month	GGT down 28.6%, blood pressure and weight also down, in drinkers without dependence	One UK study
First 30 days	Sleep recovers only in part in people with alcohol use disorder	Review
Months or years	Alcohol-related fatty liver may be reversed	Liver UK: may be reversed over months or years. NHS: the liver can usually recover
Years	Risks of oral and oesophageal cancers are lower, and may take years to reach never-drinker level	US National Cancer Institute

Some popular promises have no date behind them. Clearer skin, a day when your energy “returns”, the week your immune system recovers, the exact month your blood pressure settles: none of these has a timetable in the guidelines and reviews above, and calendars that give one are guessing. The NHS does list saving some money among the benefits. Your own bank statement will tell you how much.

What if the first days are too hard to do alone?

Message us before you stop, not after the first bad night. If you drink every day, plan the stop with a medical detox in mind, because stopping suddenly can be very dangerous if you are dependent (NHS). Things can feel worse before they feel better. That is withdrawal, and it is treatable when someone is watching.

At Renewed Life Center you are not left to get through it on your own. The first days are watched by nurses around the clock, our resident GP carries out the medical assessment and therapy starts in the same house. Kerry Dominie-Williams, a TRE (tension and trauma release exercises) practitioner at the centre, describes what carries people further: “Support, connectedness, and a framework is going to carry us a lot further.”

The rest of what stopping gives back is easier to reach once someone has seen you safely through the first week. If you are still deciding how to begin, the five-minute AUDIT questionnaire is a starting point.

Why do people in Cape Town choose Renewed Life Center?

Because for alcohol the medical side and the therapy are in one house. Alcohol was the main reason for 26% of admissions to specialist treatment centres in the Western Cape in the first half of 2025, according to the South African Community Epidemiology Network on Drug Use (SACENDU).

Dr Ruby Weber heads psychology, and Dr John Wulz is a GP who works in mental health and emergency medicine. Craig Duke is an addiction counsellor and recovery coach with over twenty years in recovery himself. Leila Bolland is a social worker and therapist who has worked in the field since 2015. John Roberts, senior recovery specialist and operations manager, has 39 years of personal recovery.

One programme from detox to aftercare. Detox where it is clinically indicated, then individual and group therapy, then the sober living programme, on one plan with discharge planning built in. Paid directly. No scheme’s cap on inpatient days decides when you go home. A written plan for home. Every discharge includes a relapse-prevention plan built for your own home environment.

Family and distance are planned for. Family therapy runs in person and by video. Airport transfers at Cape Town International are included in both directions. The house is in Lakeside, about two kilometres from Muizenberg beach, with the mountain ridge directly behind it and staff on site around the clock. More on alcohol treatment at the centre.

How do you take the first step today?

Write down what you drink in a normal week and whether withdrawal signs have ever happened to you, then message Renewed Life Center on WhatsApp. The first conversation is free and confidential and takes twenty to forty minutes. Admission usually happens within three days of first contact, and can be immediate.

On the call we ask how much and how often you drink, whether withdrawal signs have ever happened, and what happened the last time you tried to stop. You leave knowing whether you need a medical detox, which phase of the programme fits and when you could arrive, and the clinical assessment follows within three days. Nothing is settled without your say, and we send the fee and what it covers in writing the same day. You do not need to be sure you are dependent, and a husband, a wife or another relative can make the call for you.
