Forehead: Alcohol draws water out of the brain.  So, as the body starts to metabolise the alcohol, the drinker may feel dizzy and may well get a throbbing headache if they drink too much.

Sleep: Alcohol suppresses REM (Rapid Eye Movement) sleep. It's the most important phase of sleep so drinking can ruin the chance of a good night’s rest.

Skin: Alcohol dehydrates the body, which is bad news for the skin and complexion. It also dilates the blood vessels under the surface of the skin, leading to ugly veins on the nose and cheeks.

Ears: After drinking alcohol, a person can find it harder to hear sounds or where they're coming from. This means they can't react properly to what's happening around them. This is one reason why so many accidents involving pedestrians happen when they've been drinking.
