I just wanted to add to the food triggers--with my father it isn't a matter of just eating chocolate--he has to eat a certain amount over a certain period of time.
One brownie won't set it off, but a brownie one day, chocolate chip cookies the next, and a few M&Ms the next will set it off.
A reaction like that makes it really hard to pinpoint the cause. Somehow I don't think many of us are going to encourage that kind of diet for our kids :LOL
Obviously this won't work for your dc, but in my family we've found that 2 cups of HOT tea, 2 sudafed, and 2 anacin (asprin with caffiene) can make things survivable.
I have never taken migraine medication--mostly because although I am incapcitated by them, I've rarely had them in dangerous situations (driving is the worst, imo) and I can usually stumble around the house with my eyes squinted shut and reminding everyone to whisper.
When I was a kid, I would go in my room and cover the windows with blankets (shades let in too many cracks of light), put a towel under my door (cracks of light are baaaaad), and just lay there.
Now doesn't that sound like fun?
But it worked. We never found what triggers mine, although not drinking enough water definitely contributes.
Actually, now that I know more about 'nutrition' I wonder if it is the water, since when I was in college I found that drinking lots of gatorade really helped a lot once I did get a migraine.
Have any of you read Robert McCammon'sUsher's Passing
? It is a horror book, but not gory, and describes so perfectly what life is like when you have a migraine.
The heightened light and sound sensitivity, nausea, etc.
