Wow, Kylie, I think I have the exact same obsession as you!! Myself, first thing I do when I walk in the door is straight to the food. Even if I've just been out for a big dinner, doesn't matter. My parents were once at my house when I arrived home from work, and watched me get my dinner ready.... they said they had never seen me move so fast, I was like a whirlwind, or a thing posessed!!!
LOL, the only thing I can suggest is to try to do something else... like cleaning. There's always something that needs to be cleaned!! Or some kind of hobby or other interest, something that you can't eat and do at the same time.... like, if you're patient enough, some kind of art/craft where you can't have food around it. Sorry I'm not much help, I'm in the same boat
