Garlic is a neurotoxin. You can look it up. Dr. Beck spoke of this.
I was eating a clove a day to fight against infection. Come to find out my brain fog was associated with eating garlic since it can pass the brain blood barrier.
I would recommend stopping the garlic. As your died off could be related to the neurotoxin getting into your brain.
If you have ulcers(Some of us do and don't know it) The garlic can get into your blood stream. And pass the blood brain barrier.
