It is very much like a drug high. When you're madly in love, you think this person is more special than anyone else on Earth. You focus all your attention on them. You have personality changes. You're willing to take great risks to win the person's affection. And you have a tolerance level -- you see the person a couple of times a week at first, and that's OK for a while, and then you've got to see them every night.
