As I hear this commercial, the narrator means that you take 2 instead of 8 pills - one fourth of the number of pills - not that you take pills one time a day instead of five times - which is four times fewer. Obviously, the narrator is using 'times' in the arithmetical sense and tries to invert the multiplication by adding 'fewer'. I hate that.


As tsuwm points out, fewer pills does not mean less medicine or less pain relief. If I'd just quit grinding my teeth, I might have fewer headaches.
