Err... I'm not trying to sound snarky at all, and as somebody with raging un-curable tinnitus and other severe health ailments, I can definitely relate and feel awful for your loss of smell.

But like... are you sure you weren't some sort of super-smeller before hand? I don't appear to have smell issues (I believe) - but I definitely don't experience the subtleties you did, and that's coming from a person who obsesses over the fine details of things. Maybe I have some slight smell issues...
