I never really get headaches but i've had one since sunday just a little back ground one which is steadily getting worse. I'm not dehydrated and the only reason i can think for having one is all the bloody reading i've been doing, so....
What are your cures for headaches

Things i've already tried: i've been for a walk and drank loads of water and eaten loads of fruit. Unfortunatley i cant go surfing (although fingers crossed for the weekend) and i cant do any less reading.
Any suggestions, tried and tested or experimental would be good.
Oh and dont just say paracetemol or weed (Papa)
