Much Period, Little Sleep

I have to be somewhere early tomorrow and it's the early AM and my uterus wants to kill me! Well, actually, it's just doing its job... but still! Even if cramps aren't that bad, some nights I can't sleep when I'm on my period. (Case in point, tonight) How do you girls help ease sleep when on your period? I don't want to rely on sleep medication because it's only a day or two of my period and I don't want to mess up my hormonal cycle for normal sleep. Also, I take pain medication for periods already, so I don't want to add in more pills. I know masturbating can induce sleep thanks to the hormone Prolactin released afterward, but if you're not in the mood then what? I also don't feel like eating a snack/drinking warm milk because I'm queasy from period-ing. Suggestions?
