I am so sorry to hear how badly you are suffering with your migraines. I got them every month during my menstrual cycle and can absolutely appreciate how difficult it must be, I struggled then as I have a 3 year old daughter, but for the moment since I fell pregnant they have not come back. I honestly don't know what else you can take other than the herbal head balms you can rub on and the low level painkillers which I imagine are not doing much to help.
Hope you get some relief soon!!
