have tried a whole bottle of cypro, a lot of liver, pineapple and nattokinase. maybe the latter 2 not extensively enough, but so far nothing's moved the needle.
levetiracetam sounds promising, but the health system in my country is garbage. a friend of mine recommended i try naltrexone to recover my sense of smell, since it worked for her mother. doctor stonewalled me despite agreeing that it sounds like it would help. if i manage to find a more loose doc i'll look into it.
