I want to SECOND that. My best friend of 35 years was in good health and died fighting COVID. I was only sick for two days (we both had Delta).
The difference - he delayed for several days and I got right on it. I had the antibodies within 6 hours of testing positive at home), and I started "horse paste" that night.
Condolences for your friend, and a well done! for you. Don’t assume it’s a cold or sinuses; hammer it from Day 1.
In WA, you would have to have an official test which takes a few days to find out if positive or negative. They you have to find a place that does the antibody treatment, then get in line to wait. By then, you are likely 3 days to a week and a half into the infection, and you are on your own. Just like you are on your own if you use Ivermectin and other protocols, which you can begin immediately.
