Always so hungry and sleepy...

I've got about 10 days until my period, so I don't know if this has anything to do with this stage in my cycle. I wake up in the morning and immediately want to go back to bed, and then I'm hungry as hell the rest of the day, no matter what I eat. Luckily, I know I'm not pregnant because I haven't had sex in almost a year lol. Does anyone else feel this way? The hunger usually lasts until the day I start my period. Usually starts about 2 weeks before. And no matter how much I eat, I'm hungry 20 minutes later.

And I'm always soooo sleepy. All the time, I constantly daydream of going home and going to bed. It never seems to go away.
