I've actually started this blog in the fall of 2005. Back in 1999 when I began the paper journal, there really wasn't any such thing as a blog yet, per se. So the vast majority of these entries are going to be backdated.
Welcome to Doc's cluster headache journal. This is a place for Doc and Katy to keep a record of his cluster headache cycles and any issues related to that. It also will serve as a resource as Katy works on her documentary film project on cluster headaches.
