I sympathise Victoria as I also suffer with migraines, though not to the same level of severity, and can usually treat it with over-the counter medicines for migraine.
I did read in a UK paper that new research is showing that migraines are triggered by light and that this may lead to new forms of treatement: link removed
It's interesting because when I have a migraine I often feel that the pain is drilling into my eye.
My mother had migraine too for many years but after going through the menopause and finishing HRT her migraines have stopped. I'm sure women's menstrual cycles have an effect too as my migraines usually occur the week before my period or the week during.
Oh for a cure...
