Following New Year's Eve celebrations, many experience hangovers characterized by dehydration, low blood sugar, and headaches. Experts suggest rehydrating with water or electrolyte drinks to combat fluid loss and replenish lost minerals. Consuming a simple breakfast, rich in carbohydrates like toast or fruit, can help stabilize blood sugar levels and restore energy. Over-the-counter pain relievers, particularly NSAIDs like ibuprofen, can alleviate headaches, though caution is advised for those with stomach or liver issues.
