Hi,
My theory is that no two cluster heads are alike, and just as soon as you figure yours out, it'll change.
I'm a chronic sufferer, but my clusters are very different from most. Alcohol is not a trigger for me, but KFC's Krushems are so cold they'll trigger an attack, as will sudden, strong smells or changes of temperature, etc. Also, to little stress.
I have chronic daily headaches, chronic migraines and chronic cluster headaches. I would say a headache diary is vital to understanding your headaches. Through my diary (which I've kept daily for 7 years now) I learned that I cannot stay up late more than 2 nights in a row unless I want to be body slammed later with migraines and clusters.
I used to track what I ate & drank, my exercise, sleep, headaches and all painkillers and preventative meds I took. After a couple years I cut that back, and I now just track all my headaches and the meds I take to stop them. But, tracking this stuff showed me Topiramate was making things worse, and I can show that Magic Mushrooms and RC Seeds drastically improved my clusters.
