Not pregnant but sensitive to smells

[GingerBeverage]

I'm not pregnant but the past few days I've had extreme sensitivity to smells. Last night I couldn't sleep for ages because I could smell caramel somewhere around the bed and it was annoying me.
Has anyone experiences this outside of pregnancy?

Ever since my first pregnancy it's never gone away.

It's a curse

Oh wow, I didn't really have it that much during mine (no vomiting) and it disappeared after second trimester but maybe it's back.
