Yes, I lost my taste and smell in 2021. Acupuncture helped me. Was a long process but have both back 100%. Took almost a year to notice any difference. I believe it was up to 3 years gain it back totally.
However for the last several months I have suffered from tinnitus. I must have had COVID but didn't realize for several days till I lost taste again. Lost and came back for 4 days. But luckily I have back. Went thru my routine I did before. Smell essential oils, pure horseradish, garlic and strong spices.
Hope this helps.
