What’s up with that brain tingling, oh god yes, first sniff feeling?

You know the one. When you find a fragrance that just does it for you. It’s like angels are singing directly into your nostrils. Your brain’s pleasure centres start firing. You can’t stop sniffing it. Your mind is quiet for a second and all you can think is ‘I need more’. It’s almost better than falling in love.

What’s up with that? Is there a scientific fancy thing happening? Do you always buy the perfumes that do this to you? How many times has this happened for you?
