Unfortunately, I haven’t been able to figure out the trigger. Last year I had 3 in a row, same thing, every Sunday - but it was during football season (and I missed watching so many games because of them!)
So far we’ve ruled out alcohol (they happen both after I have and haven’t had a drink on Saturday night), caffeine withdrawl, cellphone use, and dehydration. I can’t for the life of me think of a food item I only have on Saturdays before a migraine. I’ve had my eyes checked. They don’t seem to be correlated to my cycle.
I tend to get them in clusters and this is the first time I’ve had them in a few months, so hopefully they are over with now for at least a few months more.
