I am physically addicted to Cheesecake, Root beer and Pizza. Not necessarily in that order.
Me too, at least with root beer and pizza (though I seldom have both at the same meal). I like cheesecake, but I'm sorta picky about it.

EDIT: Actually, I'm picky about root beer and pizza as well (and pretty much everything I eat, really), but while I usually can't stomach a lot of cheesecake even if I really like it, I can eat A LOT of pizza or drink A LOT of root beer at one sitting. (Maybe cheesecake just fills me up faster.)
