Food for night shift

I rely on this food to keep me awake. Green tea for the caffein and chicken essence ... Ok i admit I am vain. The chicken essence is more health & beauty purpose. Chicken essence suppose to help with the 'chi' in a person. Well, is all the chinese herbs idealogy but I am going to follow it cos I ain't getting any younger. I am sure I do not wanna look older than my age. Most of you will agree I look younger than my age but I am not going to tempt with night shift fate. It can really age someone.
