It sounds like this doctor isn’t very good in my opinion. What kind of homeopathics are you taking and what do they do?
If he is not using the unda/seroyal line of homeopathics then I would go somewhere else because this is the gold standard in my opinion.
What has he done to get the toxins out of your body? Reducing the toxins reduces brain fog…
I’d be happy to send you to my naturopath who will get you healing faster. He treats people abroad from china to brazil…doesn’t have a website though.
