Dry January sounds like a simple proposition: No alcohol. For 31 days. And some enthusiasts jump in without much planning — perhaps even hungover after a rowdy New Year’s Eve.

There is no data suggesting that those folks won’t be able to abstain from drinking, said Dr. David Wolinsky, an assistant professor of psychiatry and behavioral sciences with Johns Hopkins Medicine, who specializes in addiction. But starting the month with a few strategies in your back pocket — and with a clear sense of your goals — may help you get the most out of the challenge.

“Most of the benefits of Dry January are probably going to be related to the intention with which you go into Dry January,” Dr. Wolinsky said. The challenge isn’t a stand-in for treatment for people with alcohol use disorder, he stressed, but those who are looking to get a fresh start to the year may benefit from the mental and physical reset it can offer, and the opportunity to adopt new habits. For instance, a 2016 study found that six months after Dry January ended, participants were drinking less than they were before.

We spoke to Dr. Wolinsky and other experts about some strategies for a successful month.

Tell people about your plan.

One of the simplest steps is to spread the word among friends and family that you intend to take the month off, said Casey McGuire Davidson, a sobriety coach and host of “The Hello Someday Podcast,” which focuses on “sober-curious” topics.

Research has shown that accountability can play a critical role in helping habits stick, and you might find a friend or partner to join you, Ms. Davidson suggested. Even if you don’t, you may be surprised by how encouraging people are of your goal (though she said you should share it only with people you trust).

“Dry January gives people a period of time when they can stop drinking with community and support,” she said, “without a lot of questions.” Ms. Davidson also recommended reading books that may help you evaluate your relationship with alcohol, or listening to sobriety podcasts.

Identify your triggers.

Habits tend to be cued by certain environments or situations, explained Wendy Wood, a professor of psychology and business at the University of Southern California and the author of “Good Habits, Bad Habits: The Science of Making Positive Changes That Stick.”

For instance, “you have a toothbrush ‘habit,’” she said. “You put your toothbrush in a certain place. You brush your teeth usually at about the same time in the morning in that place.” Dr. Wood said that for many people, drinking habits are shaped in a similar way.

“Understanding where it is that you typically drink, who you’re with, what you drink, and disrupting those cues — disrupting the context in some way — is really critical to changing habits,” she said.

It may help to jot down observations throughout the month, Dr. Wolinsky said, recommending three columns: What was the situation in which you wanted to drink? What were your thoughts about drinking? And what did you do instead?

Find friction points.

Building extra time or effort into an activity that is typically seamless for you — such as pouring a glass of wine when you walk through the door after a long day at work — greatly reduces the likelihood of engaging in that behavior, Dr. Wood said. Something as simple as moving your wine glasses to the back of the cupboard can create just enough friction to help you achieve your goal of abstaining.

Similarly, Ms. Davidson recommended removing all alcohol from your home before Jan. 1, or at least your favorite drinks.

“I was a red wine girl,” she said. When she took a break from drinking — a break that has lasted eight years — Ms. Davidson told her husband: “I can’t have any in the house. If it’s sitting on the counter, there’s no way I’m not going to pour myself a glass.”

Make a plan for self-care.

All of the experts recommended thinking about what you will do during moments when you would otherwise be drinking. So, instead of mixing a cocktail to relax before bed (which can disrupt sleep anyhow), you might try deep breathing or brewing a cup of tea. It may take some trial and error to find satisfying alternatives.

“Give yourself grace” in the coming weeks, said Khadi Oluwatoyin, founder of the Sober Black Girls Club. Make time for rest to the extent you are able. And don’t take on too many New Year’s resolutions, she suggested; for instance, doing Dry January while adopting a new diet may be a recipe for failure. Some people slip up simply because they are hungry, Ms. Oluwatoyin said: “Go get something to eat!”

Ms. Davidson recommends rewarding yourself, either at the end of each day or the end of the week. Fun activities or indulgences can help the month feel like less of a slog.

“This is a period of experimentation and curiosity,” she said. “Instead of going to a bar, can you get a pedicure or massage on Friday night? Or get takeout sushi and plan a movie night with friends or your partner?” These “tiny shifts” can give you something to look forward to.
