Not sure if you were already welcomed, but if not, welcome to the boards!
Anyways, I'd say bring as much medicine that you feel comfortable with, then if you run out (or lose it) resort to foreign pharmacies. It's not that other countries don't have good drugs, its just that its a pain in the ass medically locate something that you need quickly in another language.
If you need to get prescription drugs in another country, make sure you have travel insurance, and find and get a local english speaking doctor to prescribe something for you. I dont' think medical notes work across borders - since I don't think if someone showed up at Shoppers Drug Mart with a note written in Korean, it would be accepted.

Vincent: "What you mean 'walk the earth'?"
Jules: "You know, like Kane in 'Kung Fu'...go places...meet people...get in adventures."
