I personally subscribe to the 'walk through' method: 2 light taps on the atomizer into the air about a foot in front of me followed by promptly striding through the resultant mist (in a manly manner.)
I can barely ever smell my own cologne but I am often complimented on it, same as being stuck in a small place with a bad odour: you cant smell it after a while cos your brain tunes it out but its still there.
