BMJ is a fine journal. I'll have to look at the study.

Edit: you summarized their opinions appropriately (this is an opinion article). I disagree that "stop when you feel better is an appropriate message." Infections can recur if you stop an antibiotic too soon, and "when you feel better" gives people too much wiggle room in that regard.

Their desire to minimize unnecessary medication is good, and supported by data, and as such they should be advocating more study as to appropriate dosing of antibiotics to allow physicians to make more targeted prescriptions. Allowing for significantly shorter durations of exposure. Rather than telling people, well you decide when your cured. It's just difficult to know if the infection is beaten back enough...
