i've experienced the same effect as you weirdos
, especially if the thing i'm cooking requires a long time and a lot of tasting and adjusting spices.
the only remedy i've found is to get some fresh air for a good 10 minutes or so, change out of the clothes in which you've cooked, and have a glass or 4 of wine.
the fresh air and change of clothes seems to clear the nose, and the wine kick starts the appetite. beer works too, but not as well.
i worked at burger king for a short time when i was a kid. i went home with the smell of stale burger and french fry grease on me every night, and couldn't wait to take a shower and get out of those clothes.
i didn't have a fast food burger for more than 10 years because i could detect that smell. to this day, the smell of old or stale cooking fat it makes me a little queasy.
