i am really tired and there is 4 hours left in my work day... how do i stay awake?

Play on the internet...try yahoo answers.

If you sit at a desk all day, get up and walk around. If there is someplace cold you can go into (or outside), go there. The cold air will help you wake up. The worst thing to do is eat. If you are thirsty, drink something with caffeine. Keep your mind as active as possible. The feeling of tiredness will pass before you go home.

Coffee and go visit somebody in the Sales Department. Usually their energetic BS can keep somebody awake for hours.

Go outside and take a short walk in the sunshine. Exposure to sunshine will release endorphins and other nice chemicals into your brain and keep you awake.

Take a short nap if u can..Apparently there are some companies that encourage a nap thru the day for employees..Makes em more productive

caffeine, loads of it ;) In case you would rather have no caffeine in your system, try a little walk to the restroom, copy room, etc. It will get your blood circulating faster and hopefully it will help to pass the time until you can quit for the day ;)

cold water

Coffee break and am up for it, are you?
