LOS ANGELES, CA -- Eyes glazing over in front of the computer screen? Nodding off at a meeting? Headed to the vending machine for a mid-afternoon pick-me-up? You're not alone. Packed schedules can make it all too easy to fall asleep on the job. Here are some tips to help you feel energized throughout the day.

1. Start with a healthy breakfast. Studies have shown that eating breakfast improves alertness and concentration and helps you feel better, both mentally and physically.
2. Don't just sit there. If you're stuck at a desk all day, get up and walk around as often as possible.
3. Eat a light lunch. Eating a huge lunch may make you more likely to nod off during that afternoon meeting.
4. Skip the sugary snacks. Keep your desk stocked with snacks that will give you lasting energy.
5. Get enough sleep. Two-thirds of adults suffer from sleep problems, and many Americans don't get the minimum amount of sleep needed to stay alert.
