I have a water bottle on my desk at all times always. When i'm in power gamer mode I usually eat normal meals but i usually don't bother unless the food gets put in front of me or my stomach starts to eat itself.
Ill be sitting in my green sofa chair, I can never lean back playing games, messes up my aiming drinking either Jamesson or Torres 10 eating cheese or salt & vinegar chips
ill be sitting in my leather recliner , playing vew vegas on my 50 inch lcd with surround sound, eating subway at first then proberly nothing till realy late at night
