Same experience here. After finally treating it (current blood pressure - 96 / 56) my number of headaches of any sort has declined dramatically. It used to be just a normal event that I would lose a day+ a week to monster headaches, where now I have close to none.

One strange thing: In the past I'd get auras and then not long after an enormous headache. I still occasionally get auras...but then it just resolves and the day goes on normally. Very strange.
