There are lots of great reasons to decide to go "dry" in January and give up alcohol. Perhaps you imbibed a bit too much over the holidays or want to start a healthy routine and can't afford the calories or the zap in energy and motivation that drinking can bring.

"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.

What is the advice from experts on how to have a successful "dry January"? Read on.

It helps to be clear about your goal to make it a habit, said Wakeman, 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 clearheaded and having more energy," she added.

Many of us may be familiar with SMART goals from work or school settings. They are used to help people set attainable goals. The acronym stands for:

"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."

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 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."

Drinking is often associated with social gatherings or fun times. That can train your brain to see alcohol as a positive. You can combat those urges by replacing your drink of choice with something equally festive or flavorful, experts say.

"For some people it can be just sparkling water, and for other people it's actually having a mocktail or some sort of (nonalcoholic) drink that feels fun and celebratory," Wakeman said.

"Substituting one behavior for another can work because you're tricking your brain," Hafeez said. "That can absolutely help you avoid temptation."

An entire industry is devoted to making nonalcoholic drinks that taste (at least a bit) like the real thing. Some even claim to have added ingredients that are "calming" or "healthy."

"I'm skeptical of anything that claims to relax you or have amazing health benefits that comes in a glass regardless of what it is," Wakeman said. "But if it's an alternative that allows you to feel like you're not missing out on a social situation and helps you make the changes that you want to your alcohol consumption, I don't think there's any downside to that."

Even if you don't end up cutting out all alcohol, tracking your emotions and urges to discover your triggers can be helpful, Wakeman said.

"Even just measuring your behavior, whether it's alcohol or exercise or your diet, can be an intervention in and of itself," she said.

"Even if someone's not yet ready to make changes, just keeping a diary of when you're drinking, what situations you're drinking more and how you're feeling at those times, can really help you identify sort of trigger situations where you may be more likely to drink," Wakeman added.

There's an additional piece that's important in accomplishing a "dry January," experts say. It's important to notice if you - or a loved one - are showing any negative symptoms from cutting back or eliminating alcohol. It could be a sign that you need professional help to reach your goal.

"The first thing to be mindful of is whether or not you actually have an alcohol use disorder," Wakeman said. "If someone's been drinking very heavily ev

ery single day and is at risk for withdrawal symptoms, then it can actually be dangerous to stop abruptly."

A person with an alcohol use disorder, who has gotten used to having a certain level of alcohol in their body every day, can go into withdrawal and experience severe physical symptoms such as shakiness, sweating, rapid heart rate and seizures.

"That would be a real indication that you need to talk to a medical professional about getting medical treatment for withdrawal and not stopping on your own," Wakeman said.
