This adult drink is an age-old nighttime cold remedy. Since you won't want to drink black tea and all that caffeine before bed, make a cup of hot herbal tea. Add a teaspoon of honey, a small shot of whiskey or bourbon, and a squeeze of lemon. This mixture may ease congestion, soothe your throat, alleviate your cough, and help you sleep. Don’t drink alcohol if you take any medications without clearing it with your doctor first. And limit yourself to one -- too much alcohol can interfere with your sleep.
