(like the times when you stare at the computer screen for 5 straight hours! ahem!)
remody: brushed teeth + iced water = a clear head and refreshed feeling.
try using a minty or cinamon toothpaste for a stronger effect and avoid the fruity ones.
drink acouple glasses of iced water
eating acidy fruits help give a refreshing feeling like oranges & grapefruit.
you can also throw in some mouth rinse (after brushed teeth) and lemon slices into ur water for an extra omph.
& Rest. - get off that computer or tv! and take a nap!
i randomly thought of this when i one day got the headache and i'm so glad it's worked ever since! i live by it! & dairy prodocts are a no-no. (i wonder if an ice pack to the forehead works...)
