When I began having migraines with my first pregnancy I started reading up
on them in my oooooold nursing books.  One thing that caught my eye was that
dehydration can be a triggering factor.  Since I was working and didn't have
time to eat, drink or potty, it was really a factor in my case.  I bagan
carring a water jug close by during hot days and since then have had many
few migraines.  I don't think I have had one in a couple of years
and not at all in my last pregnancy.  (Knock wood!)
