My mom had heard that and subscribed to it when she was nursing my youngest sister (born in 1965). Not that she'd ever had an issue with milk supply for me or the middle sister.

Of the three of us, the youngest (nursed on beer) grew up to have the worst problems with alcohol. But I'm not ready to blame the milkohol for that, since in different combinations, two of us have/had issues with alcohol, two with tobacco, and two with opiates. Addiction/CD clearly has affected all three of us.
