HELP!

Ladies I need some serious help. My crimson wave is really bad this time round. I'm talking migraines, can't keep food or water down and bad stomach pains. I'm dying for something to eat but everything I've picked either made me nauseous or throw up. I don't know what foods I should eat :(

I have tried the Pamprin Max Formula but the pain is absolutely intense still. I have to go to work for nine hours tomorrow too...Help, what should I do?

(P.s I've already been to my gyno, I do have severe PMS and intense pain. He gave me some birth control but I'm not really comfortable taking it)
