Do you notice an increase in symptoms as either full or new moon approaches? If you already have a symptom journal and sometimes can not explain spikes in symptoms even though you avoided foods and other habits that trigger symptom spikes then perhaps see whereabouts the moon cycle was at those spikes.

Roughly 50% of people that have Lyme Disease (LD) report an increase in symptoms just a few days before full and new moon.

The theory that most convinces me as an explanation is that due to the immune system suppression that the primary infections of LD (and other stealth infections) cause then roughly 50% of the people also have parasites that change their activity according to the changes in the earth's electromagnetism. That electromagnetism change is caused by how the moon alters the flow of the solar wind that the earth is inside.
