What happens after Dry January.
Most Dry January writing is about getting through the month. The more interesting question is what the month does.
There is real research on this, and the answer is better than you'd expect — with one finding that almost nobody repeats.
One thing first. If you have been drinking heavily for a long time, stopping suddenly can be dangerous — withdrawal can cause seizures, and in a small number of cases something more serious. If that might describe you, talk to a doctor before January rather than during it. There is more detail on our page about what happens when you stop drinking.
What the research actually found
Researchers at the University of Sussex have followed Dry January participants across several studies.
A peer-reviewed study found that six months after the month ended, participants were drinking less and scored higher on drink refusal self-efficacy — a measure of how confident someone is that they can turn down a drink.
A later follow-up put numbers on it. Drinking days fell from an average of 4.3 a week to 3.3. Units on a drinking day fell from 8.6 to 7.1. Times drunk per month fell from 3.4 to 2.1.
A separate study compared participants against adult drinkers who hadn't taken part. The sustained changes weren't mirrored in that comparison group.
A month is short. The effect is not.
It still counts if you don't finish
This is the finding that gets left out.
The peer-reviewed study found the lower consumption and the self-efficacy gains at six months regardless of whether people completed the month. The changes were more likely among those who finished — but they were there either way.
A 2025 review of sixteen Dry January studies reports the same thing: benefits have been observed among people who did not fully abstain.
That is worth sitting with, because the way Dry January is usually framed — thirty-one days, pass or fail — implies the opposite. It suggests a broken day cancels the attempt.
The research says it doesn't.
What nobody measures
On February 1st, a lot of people stop counting.
That is the part no campaign covers. February has no name, no start date and no hashtag. The month that gets measured is over, and the eleven that follow are the ones that decide whether anything actually changed.
Dry January hands you a measurement window. Then it takes it back.
You can't tell whether this February was different from last February by remembering it. Ordinary life is very good at keeping evidence of the drinking and very bad at keeping evidence that it stopped.
ODAAT counts the days you've been alcohol-free, and the money that stayed in your account. It doesn't stop on the 31st.
