Daughter was sick for a week, might have been covid, who knows, we didn’t test. Coughed in my face a bunch, and yesterday I felt a scratchy throat and tired.
So I gargled Lugols iodine, then did a bump of it in each nostril. (Iodine, not an actual bump).
By the end of the day, I felt normal, woke up today feeling normal.
Maybe it’s just a coincidence, but definitely felt like I was getting sick, and now (knock on wood) I feel fine.
