How long has it been? My sister in Arizona came down with "Covid/WuFlu/5G illness" in January. The doctor offered her ivemectin and she refused. Got over it without anything special. But she did lose her sense of taste and smell, and about a month ago she said that everything started smelling rotten to her and she lost her appetite. I've read about that as well, going back to posts pre-2000.

The thing with B12 is that this is only for people who were born with a natural lack of B12 at their time of birth. If that doesn't apply to you, then B12 will just be good for energy levels but not really smelling. Serrapeptase is an herbal medicine known for healing scar tissue in the brain, and is touted as something that can restore one's sense of smell and taste. So is alpha lipouic acid. Those two came up quite a lot in my research in the loss of senses due to concussions. It makes me think that whatever this illness is, it attacks the same part of the brain my wife was injured in. She was riding her bike against the flow of traffic and was hit by a car. She wasn't wearing a helmet. I'll always regret not driving her that morning because it was snowing a bit (although melting and the ground wasn't frozen). Mr. Dickbrain was probably late for work and made a turn without checking his blind spot on the opposite side of the street.
