I have done similar things...
For example when I am fasting, I don't wear fragrance, its part of denying myself any pleasures. Thant said, I have never fasted for a week, let alone a month!
To clear my senses, I find that swimming helps, and you do have to submerge for many minutes.
I have worn a lot of fragrances I did not like for 2 or 3 dyas, just to see exactly what were they thinking. It can be torture though.
