Excellent point. Barley & hops might have effects along with other things. I know as silly as it may sound.....she drinks the stuff and they bloat up, and I mean literally next day. She has always been a 2 beer a day person, and when younger larger volumes on weekends or on vacations.
Beer & the "the big daddy" the full moon at the same time adds 1.5 cups on average to her girls. In other words she will go from the ones she wears 40K or 40L, and fit right into the sizes she was professionally sized for 40M or slightly more.
Oh and BTW, she claims any beer will do, but I have tried to tell her the higher octane beer is healthier & better for the girls (maybe 1-2% more alcohol). And I know I am spot on....... based on a "professional breast observation eye" like most on this site. And those eyes say, her girls are bigger with non lite beer.
