While subtle? Thats a major bummer 
Both times I tried it I felt no change. I even sat still and tried to focus on any changes…nothing. I thought maybe it just didn’t work with me, but it didn’t even affect the people I was around at all…so…I guess it’s just a dud spray.
I will definitely test it after my long break/vacation and post up my results. Like I said, I’ll prob go up to 5 sprays
