When you're in the throes of this romantic love, it's overwhelming - you're out of control, you're irrational, you're going to the gym at 6 A.M. every day - Why? Because she's there.

Romantic love is an addiction.

The brain system for romantic love is associated with intense energy, focused energy, obsessive things - a host of characteristics that you can feel not just toward a mating sweetheart, ... there's every reason to think that girls can fall in love with other girls without feeling sexual towards them, without the intention to marry them.

I like going to the gym every day because I'm in physiotherapy every day.

The reason you take antidepressants is to feel calm. And romantic love is not calm - it's elation, it's mood swings, and you're killing all that when you take the drug.

Any kind of novelty or excitement drives up dopamine in the brain, and dopamine is associated with romantic love.
