No tips that involve being able to do much of anything, I'm afraid - just the standard dark room, cool pack/ice on the head, maybe a fan, no music/sound, don't try reading, etc. I mean, I've used over the counter migraine medication to varying success (sometimes works, sometimes it works to the extent that if I don't try to walk, I'm okay, but if I walk every step causes a wave of pain in my head), never had migraines in enough frequency or severity to go to a doctor/check out painkillers, but it sounds like you are at another level with yours. I'm sorry. Headaches/specifically migraines are awful. I don't think you are female but if you are, have you checked whether they might be hormone-related?
Hey, I read on Hubski that if the doctors give you enough estrogen, it will retard your growth. (Do not take this comment seriously, this is not intended as anything other than tongue-in-cheek meta-commentary.) My own migraines are hormonal but related to estrogen and such bullshit, so I'm afraid I have no more ideas for you :(
