30-day no alcohol challenge: a plan you can start today
You do not have to wait for January or October. Here is how to run your own month without alcohol, week by week, with a printable calendar.
A 30-day no alcohol challenge means no alcohol for 30 days in a row, starting whenever you choose. A month is the best-studied short break: in a BMJ Open study, 94 people who stopped for a month saw insulin resistance fall 25.9% and systolic blood pressure 6.6% [1]. Dry January participants reported saving money (86%), sleeping better (70%) and having more energy (66%) [2]. Plan the first weekend, decide what you will drink instead, and track the days. If you drink heavily, see a doctor first.

Set your rules before day one
- Thirty days in a row, or a calendar month? A calendar month is easy to remember. Thirty days from today lets you start now.
- What counts? Decide in advance about alcohol-free beer and wine, which can contain small amounts of alcohol, and about cooking with wine.
- What happens after a slip? Decide now, while you are calm: carry on and finish the month, or add a day at the end. Either is better than giving up.
- Who knows? One person you tell is worth more than a public post.
Week by week
Week 1: change the setting
Clear the house of alcohol, or at least move it out of sight. NIAAA suggests keeping little or no alcohol at home as a way to cope with urges [5]. Pick the drink that will replace it and buy plenty. Plan the first Friday and Saturday evening now. Read 1 week sober for what to expect.
Week 2: get through the dip
The novelty wears off around now. Shorten your horizon to today. Write down what you have noticed so far, even small things, such as fewer anxious mornings. See 2 weeks sober.
Week 3: test it
If you have avoided a social event, try one with a plan: your own drink, a line ready, a time to leave. Our list of what to do instead of drinking has ideas for evenings.
Week 4: decide what comes next
Before day 30, decide what day 31 looks like. Carrying on, a set limit, or alcohol-free weekdays. Alcohol Change UK reports that six months after Dry January, seven in ten participants were still drinking less riskily than before [6]. See 30 days sober for what a month can change.

What a month off did in a study
What changed after one month without alcohol
Reduction from baseline in people who abstained for a month (n = 94). Bars show the size of the fall.
The BMJ Open study was observational, small and excluded people with liver disease or alcohol dependence [1]. The Dry January figures are self-reported [2]. Neither guarantees what you will feel. Both suggest a month is long enough to matter.

Frequently asked questions
What happens if you do not drink alcohol for 30 days?
In a BMJ Open study of 94 people who stopped for a month, insulin resistance, blood pressure, weight and two cancer-related growth factors fell. Dry January participants commonly report saving money, sleeping better and having more energy.
Can I start a 30-day no alcohol challenge any time?
Yes. You do not need an organised month. Thirty days from any start date works the same way.
Does alcohol-free beer count?
Decide before you start. Some alcohol-free drinks contain small amounts of alcohol. If you are avoiding alcohol for medical reasons, ask a doctor.
What if I drink during the challenge?
Carry on. One drink does not cancel the rest of the month. Note what led to it and plan for that situation next time.
How do I track a 30-day challenge?
Print the calendar on this page, or use a tracker app. Sober Girl counts your days and money saved and unlocks a badge at 30 days.
