I personally OD on IS a couple months ago (around 16 sprays) and had a severe anxiety attack at work. This was my first and pray to be my last, but still, before that little melt down I didn’t IS worked at all, then only about a month ago I tried it again and realized that it worked! 5 sprays is enough for me not to get frustrated. When things would usually piss me off, they would just bounce off and my good ol IS would just flip it off and I continue on with whatever I am doing with a smile 
I have been using it a lot more recently and running out due to this extreme overload of stress I have been burdened with recently hence the reason why I haven’t been lurking much in the forum 
Hopefully I am guessing Feb is going to be when I can officially get my feet back on the ground!
