You just aim for an aura about an inch deep. You spray a little in your hand, rub your hands together and apply it sparingly. Otherwise it's possibility that you might knock a buzzard off a shit wagon.
I used to wear massive quantities of it when I was young and no one ever said anything about it. My black concert t-shirts were saturated with it. It kept me alert. But I was a crazy bast*rd and people didn't usually say much unless they knew me. My mom sure as hell disliked it, but I wasn't ready to wear Habit Rouge at sixteen.
I rarely wear Drakkar Noir any more but it's an energizer, and you should if you like it. But if you wear too much and I smell you coming then I'll make a wide berth and allow you to pass so I don't have to smell it. And then I'll wonder, "Who was that dipsh*t with all the cologne?". Because even though it can smell pretty good, it can definitely knock a buzzard off a shit wagon.
But you can always just wear it around the house. That's the best place to wear them anyway. And depending on who's there, or if that even matters, then you can wear all you want. :-)
And try another good energizing fougere like Azzaro pour Homme.
