I've never suffered from "brewer's droop" but when I have had a fair bit to drink, I am usually more interested in sleep than sex. Two or three beers is the golden spot for me as I am frisky, I've a little extra staying power, but I am not significantly impaired. Back in the day, the wife, who is no drinker, would be good to go and a little less inhibited than usual after a strong margarita at the local Mexican restaurant.
