To get rid of a hangover fast, the most effective strategies are to rehydrate by drinking plenty of water or electrolyte-rich beverages, get ample rest, and consume healthy carbohydrates to restore blood sugar. Taking over-the-counter pain relievers like ibuprofen or aspirin can help alleviate headaches but avoid acetaminophen due to potential liver damage. Eating easy-to-digest carb- rich foods such as toast or crackers can also help while avoiding greasy, heavy meals. Additionally, some find relief by drinking a little caffeine, like coffee, to combat fatigue, and consuming electrolyte-rich drinks like coconut water or sports drinks may speed recovery. Overall, hangover symptoms typically improve with time, rest, and hydration, with no true instant cure available.
