I had my fourth Covid infection just a month ago. Fully vaccinated, and having had it three times before, it still hit me like a brick.
It took 10 days to get rid of the flu like symptoms, two weeks to get to semi normal, but my taste hasn't been the same since. Not entirely gone, but very muted.
If these gums were available off the shelf I would buy them in a heartbeat!
The thing that helped me is "smell training". At random moments throughout the day try and sniff things that are just beyond your ability to smell. When I was fully in covid I could just barely perceive some sensation when sticking certain bottles of spice up to my nose.
I last had Covid 2 years ago. My sense of smell came back to about 25% of what it used to be. I describe it to people like distance. Like when a neighbor a couple floors below in an apartment building is cooking tomato sauce and you can smell it a bit by your apartment door. That's what it smells like when my face is over it cooking.
I'd definitely try this gum.

How long ago? Covid vaccine efficacy drops significantly over time so if you haven't had a booster recently, you are not vaccinated: https://www.nih.gov/news-events/nih-research-matters/why-pro...
Which that reminds me, I should schedule a booster since I'll be attending a party and a wedding soon.
