6mg ivermectin should be more than enough as precautionary for covid I think.

I only stumbled onto my awful herx reactions because I was around people who were recently vaxxed -- me being unvaxxed. Had all the symptoms, chest/heart inflammation, blood clots/heavy blood coagulation in the legs, difficulty breathing, chest rashes, dizzyness, stumbling, muscle fatigue/weakness, etc. Felt like I was going to die.

My symptoms got so bad that I ended up justifying a higher dosage of 15-20mg ivermectin every day until the symptoms were gone (7 days). While the heavy inflammation issues did go away, the herx reaction started coming in. Mine were heavy sleepyness, muscle fatigue/weakness, dizzyness, lightheadedness, light sensitivity.

Strangely enough, I didn't remember any gastro intestinal issues. Maybe super severe constipation on the day that I did end up passing them out, forcing me to slam down way more milk of magnesia laxatives than normal.

I'm going to highly assume that the parasite dying-off caused those herx reactions. I think what I ended up passing stronglyoides and candidasis threads and only feeling better once they were gone from my body.
