Ah ok took it the wrong way.
Maybe they're scared of getting sued if I become a junkie addict. And you're in America right? Maybe they're more liberal over there than here - Australia is sickeningly regulated. But whichever way, I did take offence to the doc's attitude so thanks for your comment. If a doctor doesn't do what I ask then they're insulting my intelligence and responsibility.
Actually all I want is simply Benadryl (diphenhydramine) which I bought when I was in New York mistakenly thinking they were headache pills. Of course, Benadryl with diphenhydramine is only sold as a prescription here thanks to Australia's stupid regulations.
