You know, I actually agree with the food suggestions.  Now you think, "oh, no, I couldn't possibly waste suitcase space with food stuffs," but there will come the day when you could kill for a peanut butter sandwich or an oreo cookie.  Trust me, I had terrible cravings for Mexican food while I was in Germany -- probably simply because it wasn't readily available!  (Whenever Pamela, Bridget and I would get together, without fail, we'd make tacos!)

Plus, it's room in your suitcase that will be free when you move back!  (Or, you'll do like I did and fill it up with native foods you won't be able to live without!)
