If you have a sound machine and like it (or "need it" to go to sleep), bring it and figure out how to get it to work with the electricity (usually just buying a replacement AC adapter). Also, if you like tacos and use taco seasoning, bring that as well as the only brand I've been able to find is Old El Paso and it tastes different here (if you're picky about that). If you like dill pickles, you may want to bring either a jar of your preferred brand or one of those pickling kits. Also, Ranch dressing mixes (and well, any dressing you like as I've not been able to find very many here). Oh, and the more OTC meds you can get in the US, the better as everything here comes in really small packages.
