You can't get drugs for anything here. I had a minor surgery, wanted a pain killer, doctor said "no, just deal with it". I can't even buy a Tylenol PM here, seriously. In fact if you goto the pharmacy and try to buy anything the lady will quiz you like she is your mother and ask why you need it and suggest you try sleeping more or eating good food. There's also no street drug problem here. Koreans just don't go in for the whole drug thing.
Meanwhile back in the states my mom (the original 1960's health food nut), is now on super-scary drugs for depression.
