There are those who may be addicted to that love "high." They need that amphetamine-like rush of dopamine, norepinephrine and phenylethylamine. Because the body builds up a tolerance to these chemicals, it begins to take more and more to give love junkies that high. They go through relationship after relationship to get their fix.
