I did! I am sure stout brought my milk in and beer makes you really engorged, not sure why.
Brewers yeast in good quality unfiltered beer.

DH is a keen all grain home brewer, so I drink his beer from time to time. At the moment it's only once a week, but that's more for weight loss purposes than because I'm breastfeeding.

I went to a party a few weeks ago and had two West Coast coolers and a tequila shot. Oh yes, I'm wild! Got home at 2, fed DD at 4. Had a "hangover" the next day, but I think that was from lack of sleep, sugar, and too much exposure to smoke, rather than my three standard drinks.
