Mommies with headaches.

What do you do when you get a headache from lack of sleep? I try to sleep when my baby sleeps but it takes hours for me to be able to. Once I do baby wakes up for a feeding and I'm back to trying to sleep ); I don't care if I get very few sleep I can deal with sleepiness its just those painful headaches and when my head starts to pound that I can't deal with..it makes me lash out at my.bf because I get so moody. Caffeine makes it feel better for awhile but then I get it again an hour or two later. Help!!
