Though Dry January can be helpful for moderate drinkers, it’s not recommended for those who are alcohol dependent. Alcohol Change U.K. warns “people who are clinically alcohol dependent can die if they suddenly, completely stop drinking.” Stopping alcohol cold turkey can result in alcohol withdrawal syndrome, which includes symptoms like nausea and vomiting, sweating, high blood pressure, insomnia, anxiety, agitation, rapid heart rate and tremors or shakes. If left untreated, it can progress to violent seizures, delirium tremens (a life-threatening form of withdrawal with symptoms like fever, high blood pressure and hallucinations) or even death. Instead, it’s recommended to consult a medical professional for a safe medical detox.
