I have a very addictive personality and I am addicted to the people i love. Addiction in its worst form with visual cue triggers, withdrawal and total emotional dependence. There was that science paper that showed that the the brain registers the high from drugs in a distant place from where it registers the memory and need for the drug. Based on a lot of advances in this field, where the brain circuits and centers are understood and functions mapped in live patients reponding to stimuli, there is the near promise of a drug or a procedure to zap the trigger out at once. I think it will help with nostalgia too. The ramifications of it ... Scary!
