Does anyone that gets migraines remember the first time you ever had a migraine?
Personally, I would say I can't say I know. As alcohol is one of my migraine triggers, I think the first migraines I ever had were when I was hungover. Then it changed to every time I had even a single drink of alcohol as I became more sensitive.
But when I started uni, after the first month of school I woke up with a migraine headache that didn't leave until the last six months.
