re: Weird taste and smell 8 months post Covid. Doc said to try aroma therapy

Had COVID in July 2021, Lost taste and smell a few weeks. Smell returned but not 100%. Had vaccine in late Sept (NB4 not necessary - I agree). Thought it was harmless. Then lost most taste and smell, and what I can taste is combined with a weird, nasty taste. Some things that I enjoyed have strong nasty taste, others only slight altered taste, even toothpaste, but all with the same weird taste. Lost 15 lbs due to no temptation to eat between meals since nothing taste good. I can barely even smell gasoline, cologne, etc. My shite hasn't stunk since July.
