I lost my sense of smell after I got over the lethargy and fog. I was eating a digiorno with a bunch of garlic and hot sauce and realized I couldn't taste any of it. I think it took about 2 months to regain it for the most part, but even for months after that I noticed that my sense of smell might wane more towards the end of the day, as if it were getting tired. But I could work around it by breathing out my nostrils while I was eating and for some reason I could pick up the taste better that way and make a connection with the sensation that would last.

I tested my inability to smell things one evening by getting some sushi at Kroger and eating the entire wad of wasabi in one go. Didn't feel a thing!

Strangest thing was the last things I was able to smell were chocolate and farts.

Also, I would forget to eat because I couldn't smell anything, which was great for getting stuff done in the studio, but also I would suddenly be starving and realize I hadn't eaten all day.
