Headaches are a pain!

I have had a number of excruciatingly bad headaches lately. So have a number of friends. It may be the change in weather, now that its raining and cold we are indoors with our kids a lot more. That would be enough to give anyone a headache =)
But why now? Why are so many of us getting migraine like headaches? They really are quite debilitating. Is it maybe something we are eating?

Here is a book I came across in my search to find out for myself - Are there any foods that can trigger my headaches?

This book does list a lot of food you should avoid, quite overwhelming in fact. But I did discover that it was probably dried cranberries that triggered my killer headache the other night...who knew!
