I used to not drink coffee, joined the high-end VFX industry, started to drink a lot, e.g., 3 big dark mugs at work each day. We had top-of-the-line espresso machines and great coffee so it was easy. Something I noticed is that on weekends, I had systematically huge migraines, those were soothed by drinking more coffee...

The issue is that caffeine has a vaso-constricting effect on blood vessels [1], which then, when they re-expand by lack of caffeine creates the migraines.

One day, I decided to stop, I had an horrible week, constant migraines, it eventually stopped and I never really had coffee since then. Only 2 times during conditions where I needed which added the benefit that the caffeine had a really strong effect then.

I'm certainly missing the taste and ritual, so I replaced coffee with green tea, not as good but no migraines!
