I know a few people who seemed to be sick for like a month, until they were finally talked into taking ivermectin which cleared things up pretth quickly. I literally went to tractor supply when I started feeling rough & bought the horse paste, no issues, worked shockingly fast. Someone has since pointed me to a website where I could buy the pills. I can't remember what address right this minute, maybe someone else knows a place off the top of their head, if not I'm sure I bookmarked it somewhere. Would also tell them to eat steak, & avoid sugar & seed oils. Hope things improve for them.
