Any specific foodstuff (of course what your allowed to take) teabags, sauces, (oh how I miss horseradish) even biscuits , dont know where you are now, but I made sure I had a few home comfort foods with me at first, its amazing what you get homesick for or you cannot get and use maybe everyweek to cook with
Any specific things for the first aid box, nail sccisors, clippers and the like as well and toiletries until you find alternatives . Any make up that you love again until you find others.
Underwear, I cannot say this enough, make sure you have your comfy bras/knickers/tights if needed.
Any particular brand of pads/tampax etc items, you may only like one and maybe can not get it where your off to, again enough until you find another you like.
Dont know if your off to a warmer climate or not but would be thinking of mozzie spray/cream so your not having to run out and find some locally...
Sure will think of other things soon...
