Been sprayed 3 times working for various law enforcement agencies. This stuff works really well. However the first time was the worse for me...the spray works physically on people, mucous membranes, eyes, etc. It also has psychological ramifications. Yeah, it's nasty...
Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.
Though wise men at their end know dark is right,
Because their words had forked no lighting they
Do not go gently into that good night.
