"Or it may be someone who truly is starting to wonder or question their relationship with alcohol, and this is an opportunity to really explore that," said Dr. Sarah Wakeman, medical director of the Substance Use Disorders Initiative at Massachusetts General Hospital.
"For some people saying 'I'm not going to drink this entire month,' might be really hard, so trying to do so may show you how easy or difficult it is for you," said neuropsychologist Dr. Sanam Hafeez, who conducts classes at Columbia University's Teachers College.

It helps to be clear about your goal to make it a habit, said Wakeman, who is an associate professor of medicine at Harvard Medical School.
"The research we have on goal setting says goals are more likely to be achieved if they're really relevant to you as an individual and not abstract like 'I should stop drinking because drinking is bad,' " she said.
Concrete goals such as embracing new sleep habits or an exercise routine will help make giving up drinking easier, she said.
"I really want to stop drinking because I know when I drink heavily I don't get up the next morning and I don't work out is a very specific goal," Wakeman said.
Additional motivation can come from the health gains you can make from reducing or eliminating alcohol, experts say.
"Drinking less over time can have really measurable benefits in your health in terms of your blood pressure, your risk of cancer, your risk of liver disease and other conditions, Wakeman said.
"Over the course of a month, you may notice some short term benefits like better sleep, a better complexion due to improvements in your skin, feeling more clear headed and having more energy," she added.
2. Set 'SMART' goals
Many of us may be familiar with SMART goals from work or school settings, which are used to help people set attainable goals. It stands for:
- Specific: Set an achievable goal, such as cutting back on drinking 3 days a week. You can add days until you reach your final goal.
- Measurable: How many drinks will you cut -- and what are the drink sizes? A beer is 12 ounces, a glass of wine is a 5 ounces and a serving of spirits is 1.5 ounces.
- Achievable: Make sure there are not a bunch of social engagements where alcohol is likely to be served during your month of abstention.
- Relevant: How is not drinking going to help me with my life and health?
- Time based: Set a reasonable time frame to finish your efforts. If you like, you can set another goal later.
"If you set a bar too high, you may fail, so it's better to set smaller goals to achieve it," Hafeez said. "Nothing starts without an honest conversation with yourself."
3. Share your goal with others
Informing a few friends or family members of your goal can help you reach it, experts say. For some people it may work to announce their plan on social media -- and even invite others to join in and report back on their progress..
"That's where I think 'dry January' has kind of caught on," Wakeman said. "If you publicly state you're going to do something, you're more likely to stick with it than if you keep it to yourself."
4. Consider a 'mocktail'
