Is drinking more coffee, giving me migraines?

Unfortunately my insomnia is making my life difficult. I'm mot eating properly either. Coffee is the only thing keeping me going.

But I've been getting mirganes more and I'm drinking about 2 to 3 cups of coffee daily, when it used to be 0. Is the coffee casuing my migraines? Is the lack of sleep and food not helping?
