It seems that lately, questioning the "doctors" in public places can make you a pariah (and I won't go any further with that).
On another note, I was prescribed a medicine 20 years ago called Propulsid. When I went to fill the prescription, the pharmacist told me that he would not recommend I take it. I contacted the doctor and he was pissed that the pharmacist had given me that recommendation. In the end I didn't take it, which is a good thing because it was removed from the market several years later for causing heart issues.
