Day 3: Take a Multivitamin for Energy
Multivitamins contain key nutrients to support overall health and keep your immune system strong so you can fight off illness. If you’re a pre-menopausal woman and/or still have your ovaries, you’ll want to take one with iron otherwise you no longer need this nutrient in supplement form. (You may want to discuss with your doctor.) Take a multi every morning that contains:

• No more than 3500 IU vitamin A
• No more than 30 IU vitamin E
• And 100% daily value of other vitamins

Day 4: Get your Rest
Everyone’s goal should be to get seven to eight hours of restorative sleep. If you’re not getting this amount, try to manage your time better so you can carve out just an extra hour of shuteye. Habitual sleep loss by even one hour can lead to chronic drowsiness.

Day 5: Zero In on Hydration
Your body is a machine made up of two-thirds water. Since we are comprised of so much fluid, even slight dehydration can leave you feeling lethargic. Try Dr. Oz’s "Wakeup Water." Make a pitcher each day that contains:

• 8 cups water (to stay hydrated)
• 3/4 cup cooked pearl barley (contains iron to fight fatigue)
• 2 lemons (for antioxidants and vitamin C)
• 1/4 cup honey (to make it palatable and sweet)

To make the beverage: Add barley to boiling water and soak for 10 minutes. Strain and remove barley from the water. Add the juice of 2 lemons and a quarter cup of honey. Try bringing a portable pitcher with you to work. (You can save the cooked barley for dinnertime.)
