How can I keep my head clear while working?

Focused. During work I am sure your mean focused; a clear mind would be unproductive. Having a clean, organized workstation will assist in a focused mind. High protein and free fatty acids (omega 3, 6, 9) as well as vitamin/mineral supplementation helps the brain to overcome add and remain focused. Essential oils of citrus are effective.
