Carrie is an on-off smoker and when she smokes, she is mostly seen with Marlboro Lights. She tries to quit in seasons 3 and 4 using a nicotine patch while dating Aidan. She enjoys cocktails (particularly cosmopolitans—her character's fondness for them helped to popularize the drink). While Carrie is a realist about the difficulties of relationships, having experienced many bad ones throughout the course of the series, she is a romantic on an endless search for true love, and refuses to settle for, as she puts it, "anything less than butterflies." Because of this, she repeatedly expresses doubts that she is the type to get married and raise a family.
