How can i stay energized longer at work?

what worked for me was staying away from sugar and carbs..I would stick with a protein lunch with high fiber....and I was able to increase my energy level. Coffees, teas, all that stuff...they are stimulants, but not particularly healthy. Try to drink Ice water and healthy proteins and high fiber..you'll see a difference. Great Multi vitamin and believe it or not, but fish oil pills each day..can't go wrong!
