Here is what I mentioned in krnel's post regarding this BMJ journal:
"the "full" course, it is vaguely described, if a doctor prescribe a two days course (which in the past might be 10 days), the post of not taking the full course become misleading!! "

I do agree that we might need to optimize the dosage of the antibiotics treatment, but people misinterpreting the "full course" will be fatal.

I will still recommend people to finish the prescribed dose, as probably most of us are not medical doctors, and failing to take appropriate treatments will likely mean we miss the golden treatment window, it is always us that suffers in the end.

MOST IMPORTANT OF ALL:
let's not take the journal "quality" as a standard reference, we all have seen that Lancet published the antivaccine paper which they later regretted it ; ]
