Plan B is irresponsible. It is an emergency pill. If taken to often or too much it can have sever impacts on a woman's body and how she can reproduce. I believe that the pharmacist was in the clear. If you came in that soon after already having bought it once before that is a very immature decision to be making. If you're having sex that often you should be on a more effective and safer form of birth control instead of the Oh Shit Pill.
#6 - You're not too bright if you're condoning taking the pill as often as need be considering the side effects there are from taking the pill too often. It's not advised to be pumping your body full of those hormones often. They can severely disrupt a woman's menstrual cycle or even cause damage down there (from what I've been told anyways from an MD).
