My daughter gets migranes. I have never suffered in my life.
Just blinding headaches like an iron band being tightened around my head or a heavy thumping inside, or even a gente one like now. No idea what causes them although there was a possible diagnosis several years ago.
The old annual confidential had a little box -DRINKS - that the boss could mark, Does Not Drink, Drinks moderately, Drinks heavily but sensibly, Drinks heavily and unwisely. I think this was the one line where the high score was for DHU.
