Everyone's body reacts differently to new foods and eating habits, as well as to new environments.  Some people gain weight, others lose it.  Some get a little sick from trying new foods, others can eat anything and not get sick.  It may take a few weeks for your body to adjust to the new ingredients you will be eating.  But don't let your fears get in the way of tasting new foods; that is half the fun of learning the new culture. Pepto Bismol or other medications usually do the trick when you are sick.  You may want to take your favorite over-the-counter medicines (i.e. aspirin, Tums, etc.) for the first few weeks until you are comfortable with the surroundings and language.  If you are ill the first few days, it may be too stressful to try to find the items you need while attempting to negotiate your way in a new country. If your illness persists, let your faculty director, program assistant, or resident director know so s/he can help you access medical care. Don’t be afraid to ask for this help!
