It usually happens around 3 p.m. Your eyes get a little heavy, your energy starts to sag, and you feel like you need a nap or something to get you through the rest of the day.

3 Ways to Keep Your Marriage Clicking

By Lindsey Palmer You know the feeling: You're introduced to someone new and — boom! — you're instant pals, or you meet a man and — sigh — it's love at first sight.

1. Hydrate Yourself

Staying hydrated is essential to maintaining energy. So before you head to the vending machine in search of a pick-me-up, drink a big glass of water.

"As we age, our thirst mechanisms are not as reliable and don't work as well. Keep water bottles at your desk or in the car, and sip regularly."

If water just doesn't do it for you, try a glass of iced tea or cup of hot tea.

"It makes sense that cultures around the globe have enjoyed the daily ritual of 'tea time,' to enjoy a hot beverage and a little snack to perk up their sagging energy levels." says O'Neil.

Having a cup of tea helps hydrate you, and the addition of a small cookie or dainty tea sandwich is just enough to take the edge off your appetite and energize you until dinner.
