I once tasted my friend's when i'd just eaten a pear. Pears are sweet and refreshing compared to human milk LOL. I found after a run (or an arguement of which there were MANY in those days) my milk tasted off and my left boob (which always had less milk in it) always took longer to recover. Do you drink a sports drink at all? My GF uses those little sachets of electrolytes and her DS (age 18 mos) refuses her milk for about 12 hours afterwards.
