The fact that so many people are looking to get drugs without a prescription makes me reflect on the accessibility to healthcare in this country....
If you really want to get right down to it, why are guys in special forces (arguably reasonably smart, also evidenced by their figuring out this antibiotics trick) NOT going to see an army doc right away?
If I was going to be a really snarky asshole I might suggest that perhaps because it's a single-payer system the quality of care isn't that great and blah blah blah. I don't really believe that but arguments can be made both ways.
Don't be a troll.
More generally, what makes sense for your career sometimes negatively affects other areas, but we tend to protect our careers.
