Simply eliminating these from my diet has helped cut down migraines from 2-3/month to 1 in 3 months
Then afterwards you can find an ingredient you might think is the culprit.
The ingredient may also take a few days to affect you, so you have to allow for that.
This might be my case ( whole I think I'm lucky enough that it is not a real big issue.) I remember drinking despados ( some kind of tequila and beer drink.) And having a huge headache the day after. And getting them once in a while. I connected it somehow to the beer and stopped drinking it.
That might be the cause... I need to keep an eye on that. Thanks for the tip :)
