I'm 100000% cured, I would know. I used to get hateful remarks and dirty looks anywhere I went and I would stink up rooms (I could never smell anything).
At most, sometimes I could smell it for 1 second (literally) and then not again for a few days, maybe even a week.
I told family and they thought I was crazy even though I tried to tell them that for some reason people you live with can't smell it.
I can walk anywhere now, drink alcohol (which used to make it MUCH worse), play sports, whatever. I even had a doctors checkup in June/July to make sure I was fine.
