What does a sleep aid pill have to do with relationships? Read the accounts of the author of this article and her relationship with "Sam":

Sure, he was a critical jackass by the light of day, but by the warm glow of a small yellow pill and a single malt scotch, he was a gallant suitor, a crooner of sweet nothings, my accessible, chatty fiancé-to-be. He would call every weeknight around 11 p.m. and it was just like it was in the heady beginning of our romance. He would embarrass me with compliments... About six months into the relationship we spent a winter weekend at his uncle's house in Connecticut, where he virtually ignored me until the blessed hour when he could slip himself a Mickey. Then he would sidle into bed, cuddle and -- the ultimate aphrodisiac -- talk... And then we would have the sweetest, nuzzliest sex... Until the next day, when he would suggest I wear lower heels and we would have angry, argument-fueled sex... Let me be clear -- Sam was never abusive, he was often funny, and he was unfailingly smart. But he was not a warm guy, unless aided by the chemical collision of zolpidem and booze... I didn't know that Ambien was the wellspring of his devotion.

I posted this because this might ring a bell with someone and also to show how drugs -- even the ones you'd never think of -- can impact personal behavior in ways that are hard to predict.
