The most effective way to conceal the scent of alcohol is to eat equally stinky foods. Try eating foods with garlic and onion for breakfast. Some ideas include: Breakfast omelette Savory breakfast scones Savory crepes Another stinky consumable item that is effective at covering the smell of alcohol is coffee. Have a cup of coffee in the morning, and continue drinking coffee throughout the day. If you are sensitive to caffeine, switch to decaf. Be aware that coffee breath can be offensive too. Peanut butter is also effective at concealing alcohol breath. Consider packing a peanut buttery treat in your lunch for the day. Some ideas include: Ants on a log Peanut butter and jelly sandwich Noodles with peanut sauce Drinking plenty of water is the best way to flush out your system and eradicate (rather than just cover) the scent of alcohol. Aim to drink half of your body weight in ounces. For example, if you weigh 150 pounds (68kg), try to drink 75 fluid ounces (2.2l). Good news: water is also the best cure for a hangover. As your body metabolizes alcohol, the scent can reappear on your breath. Help to keep it at bay by regularly chewing gum or using breath mints throughout your day.
Eat foods with garlic and onion. Drink coffee. Have peanut butter for lunch. Stay hydrated. Chew gum throughout the day.
