I have chronic migraines (53 years) but now that I have eliminated most of my food triggers, they aren't the worst type anymore. I have noticed a pattern change this summer. I have always gotten them around 3 am. If I am lucky, they don't get much worse. Typically, I have "good" weeks and "bad" weeks. Same diet. Now I notice that some are starting at 5 am or not until 4 pm which is rare. So, I'd like to know what causes pattern changes. Age? I have read that some of us get better as we age. I am hoping this is the trend I am experiencing.
