I was doing some research on headaches, so I thought I would share it with the blogoshpere 
I have added a health information section to the site that pretty much covers everything I found.
It covers everything from Migraines (which, Thank God, I don’t have) to stress related and chronic headaches (get them rigth enough 
)
Here it is: Headache Information
(added:)
Actually, whilst I was researching the headache articles, I came upon something really useful information on cluster headaches
It seems this is what I used to suffer from back in 2001 - I never knew it had a specific name!
