I get lots of PM with medical questions, and I try to answer them correctly. But I don't feel PM's belong on a public board. And I don't need gh15's advice, I'm a MD and can get all the drugs I want. But you are kiddin', of course... 
Sometimes there are things you would like to discuss private, but I'm not a frequent user. Of course I was kidding, asking for sources is like begging for being excommunicated.
