I’ve had this for the past 6 months. I’d honestly rather have entirely lost my sense of smell than to go through this.
This happened to my wife. It was torture for her for the first year. It's been almost 3 years now and she's just barely starting to enjoy food again. Most things taste fairly normal for her, but a few things, like mint, onions, and garlic, (which are in everything, unfortunately for her) are still wretched.
