Usually I don't smell myself either, I can smell it rarely. This belief came to my mind cause my body also changes, I feel more fresh and healthy, I can feel it. Additionally almost no one complains about the odor in that time.
So it has nothing to do about my nose because as I said I don't smell myself. And yes you are right when it dies it smells more and more.
There is no possible cure without doing the diet so I changed my priority. If I can prevent the smell this will be enough for now.
