hi,
I though I would share some of my research on perfumes and their use as triggers, sort of.
I have been in search of the orginal pampers scent. Alas, no examples exists so you can only work from memory. were taking pre 1990. Pampers went unscented after that time, then returned with a new powder scent which they use now. The original scent was more in the category of female perfume. I know I have detected similar scents in public which leads me to beleive there is a commercial scent that is close, but I have yet to find it. A great site for sampes is the perfumed court and the demeter fragrance library and Clean. Google them.
I beleive a very simple script could use perfume as the trigger or enforcer to make you wet your diaper. The nice thing here is it occurs randomly. All of a sudden you get a hit of the scent and you remember.
I would suggest choosing a scent that has a strong note that you can latch onto. I would not suggest babypowder as you are probably already conditioned and used to that one! My mom liked chanel #5 and I found that one to be very interesting as well.
Demeter's Laundry and Clean's Warm Cotton are both very nice. Demeter has some odd ones too like vinyl and rubber. Have fun and share your experiences. And if any of you old timers come across a match for the original Pampers, don't keep it a secret.
