@garritfra I used to drink 2, 3 or mayne 4 big cups of #coffee during workdays. I'm pretty sure I was around 1l of the black stuff a day.

Except weekends. At home I maybe drank one cup of instant per day. Weekends were punctuated with a very strong #migraines.

This went on for at least a couple of years if not more, until I crossed the Atlantic, changed my habits by chance, and drank less coffee. Months to years later I figured it out, because of course I never asked a doctor.
