For me the smell lasts and lasts, I love the smell and am addicted to smelling it. LOL. However I believe that I have revision 23, I am not as attracted to the smell as I was when I had my first bottle. Where you place it on yourself, should depend on what effects you desire. If you want self effects the strongest, then apply closer to the nose. If you want to reduce self effects, or have effects affect others, then place drops on your wrists. When you move your hands around it should help disperse molecules. (this is not scientifically proven, however many people have reported positive results with this)
