I can alway's remember when I was in my twenties, I worked at this big plastics moulding company, part of my job was to deliver all the mail around the factory.

One of the head guys complained about my perfume, I wore CHARLIE in those days, I expect every time I left his office, the place reeked of it, I was so embarrassed

So to this day I am very aware of not over-doing it, trouble is you can never smell it quite as much as other people.

I know what you mean about getting instant headaches etc, sometimes I try the perfume's on at the counter, and regret it, because I end up shopping with a rotten headache afterwards.
