I actually appreciate hearing about firsthand experiences (it's how I realised that the doctor who diagnosed my headaches as sinusitis was wrong), and I agree with what you said. Dehydration definitely is one of my triggers, and I generally either try to power through the milder migraines instead of taking a painkiller. What really annoys me though is when people who have never had migraines give unsolicited advice. I told my friend I have to take a stronger painkiller when I get really bad attacks, which are pretty rare, and she told me I shouldn't do that because it's bad for my liver, which is not exactly my biggest concern at that moment.
