I would consider reducing the training and focus on building your immune system and not muscle mass.
I would also consider trying out acupuncture which can help you detox and rebalance the body.
I sometimes would get hit with waves of nauseau and strange dizzy like symptoms when I went through die-off, so the allicin could’ve done this. I’d also consider switching from allicin to garlic capsules, because the allicin can be hard on your liver (likely less in garlic).
My coworker has a disorder called inner ear disorder and I would look into this as well.
