headache
"I was prescribed naproxen by my neurologist for menstrual migraines that left me debilitated every month with severe vomiting.  I now take 500mg each morning and night a few days before my period is due.  I started taking this preventative treatment of naproxen six months ago.  I still get headaches and occasional migraines but they are less severe and I have no vomiting.  Before taking Naproxen I was having at least three days off work each month.  I haven't had any time off since starting the tablets - really have improved my quality of life."
