i may mention it next time i see the GP; i don't think i'll go on purpose. i've never had the sort of migraine where you just have to lie still and throw up for hours -- this was just a very, very bad headache until i realized it was the sort of very, very bad headache that came with light sensitivity. i've turned off all the lights but one, and put on my sunglasses. shame i can't actually function with a sleep mask over my eyes.
