Myself, I can tell when I am “pre-migraine” and know I have to sit down for a bit lest one develops. They most often come from eating junk food after exercise (I’m looking at you, Fritos). And warming my hands often helps speed the recovery, though I always end up with “tender brain” for 24-48h after.
I’m intrigued by another poster having success with Magnesium L-Threonate and will be placing an order today. Even if I don’t have a migraine, I have a headache 8 days out of 10.
