MOON TOWNSHIP (RMU SENTRY MEDIA/CNN) – Depending on how hard you celebrated on Monday night to bring in the new year, you may be observing National Hangover Day.

The nationwide observance of hangovers is each year on the first of January, when Americans are most likely to be feeling the effects of drinking the night before.

Symptoms of hangovers include exhaustion, a pounding headache and nausea.

If you’re suffering from a hangover, it’s best to observe National Hangover Day by getting a lot of rest, eat well-balanced meals and rehydrate with healthy fluids.
