They suck a lot! I get them often, they started in my teens and both my mother and father had them so I was a marked man.
Mine are basic, no auras, usually one half of my head (right side) front to back or back to front, throbbing most of the time. On bad days it feels like someone is in my head cleaving it down the middle from the inside while poking my right eye out from the inside at the same time. I’m usually sick as well, and sound will sometimes bug me (like being in a state where everything sounds like it’s peaking even if the volume is low.)
I have 2-4 a month, usually the lower end of that so I consider myself lucky. My triggers, at least the ones I know of are things like caffiene (which I’m NOT giving up), stress, very low sleep, low water, and to be honest I think the weather as well like maybe during a weather change.
I’ve met some folks who are much worse off than me so I am happy with only needing some heavy OTC meds and the occasional Imitrex (which is like the best thing ever!) Probably the thing that has helped the most is to always have an agreement with my workplace on what I do on a very bad day. Fortunately I’ve been able to work from home when it’s very bad so I can keep the lights low, absolutely no sound, etc.
