Craving beer and cinnamon buns

For the past month I have been craving ice cold beer and cinnamon buns. I don't even like cinnamon buns all that much. I only like them if they're warm.
I've always liked beer, even as a kid. My parents let me have non-alcoholic beer, or it may have been 0.5% alcohol or something to that effect. I loved it. My mom does as well, so I suppose I may have inherited it from her.
This past month though, the craving for cold beer has been incessant. What's even more odd is the craving for cinnamon buns. One could think I was pregnant. You could trust me to have an impossible craving such as beer, if that was the case.
And trust me to crave two highly fatty and carb-ridden things. Why can't I ever crave things like carrots or celery?
