I had them chronically as a child every couple weeks; the more standard variety where just being upright caused nausea, couldn't eat, couldn't stand light, etc. They stopped when I entered puberty, thank god.
For the past couple years I go through a phase every year for a few months where I get migraines regularly. I've had three in the past week. But they are more manageable now. I get brain zaps when I look at bright lights (like streetlights/headlights) but I can be in a normally lighted room without it being miserable. The pain is pounding and severe but not to the point of making me nauseous. Usually always on the right side. And I can still listen to things, just not as loudly as usual as my sense tolerances are reduced by 50% or so during a migraine. Caffeine actually helps take the edge off the pain, but just the edge. Sleep usually solves it but that's difficult to achieve as the symptoms actually get worse when I lay down and it constantly wakes me up.
No discernible triggers as far as I can tell. They hit suddenly and then they stop suddenly. I'll go months without a single one and then have a couple months where I get multiple every week.
