OK so are we saying they still smell it in their head even though there is no smell, or is it that there still may be a very faint wiff but this triggers them smelling it as before?
Thing about smells is you can strongly associate them with something, good or bad. Granny may link the smell to losing her faculties or death which affects the intensity of the perception.
I would try and suggest that the smell you are getting is something similar but different, and preferably pleasant.
I still keep getting a whiff of pee. Really? You know the more I smell it, the more I think it's like new mown hay, reminds me of being out in the country on a sunny day, can you smell it yet or has it gone completely?
