I am trying to be diligent with maintaining a migraine diary/log. How are others determining when one migraine ends and another begins? I hadn't really thought about it much, because they all just seem to run together. At other times I have felt one end because it would seem my head would clear, and I could honestly say it was over. Then I have bouts where everything just seems to run together and while I may be "pain free" for 24-48 hours, it does not seem the migraine is gone.
