Regarding medications, I have found that in many Asian countries you can't just walk into a store and buy the over-the-counter medications that we (Americans) are used to. If you like Nyquil, bring along Nyquil (gel tabs are easier to carry). "Baby" (81 mg) aspirin doesn't seem to exist over there. Cold-Eeze - never heard of it. (I almost always catch a cold a some point in my Asian trips - too much hot weather + frigid aircon.) On the other hand, local drugstore pharmacies will often have medications which are readily available there but prescription-only in the US.
