Helen Fisher (May 31, 1945 -)
If the love object breaks off the relationship, the lover experiences signs of drug withdrawal, including protest, crying spells, lethargy, anxiety, insomnia or hyper-somnia, loss of appetite or binge eating, irritability, and loneliness. Lovers, like addicts, also often go to extremes, sometimes doing degrading or physically dangerous things to win back the beloved. And lovers relapse the way drug addicts do. Long after the relationship is over, events, people, places, songs, or other external cues associated with their abandoning sweetheart can trigger memories and renewed craving.
