Detoxing from alcohol at home offers a number of risks, especially if you lack a strong support system of trusting, reliable friends and family. An at-home alcohol detox increases your risk for relapse despite your intention to quit alcohol for good. Many times, physical and psychological alcohol cravings can be severe enough to cause relapse even though you may plan on never drinking again. Additionally, alcohol withdrawal symptoms like vomiting, sweating, and diarrhea can increase your risk for dehydration and malnourishment. Without healthy foods and fluids like water, fruits, and vegetables, your body can suffer worsened health as a result of alcohol withdrawal.
