Thanks for responding to my answer. In regards to the covid gut, I don't think I have too many issues from COVID in that area. I have always had pain until I stopped eating all beef, pork, lamb, etc., due to Alpha Gal Syndrome. AG can be deadly and eating one wrong thing can thrown one into shock one to eight ours after consumption. Doxy was originally prescribed to me because of Lyme Disease. A lot of people cannot tolerate Doxy due to GI issues, but I do okay with the 100 mg a day with food. Doxy currently is the antibiotic of choice for COVID right off the bat, and that I why I thought, well....I had COVID, have odd long term symptoms, so made sense to me to dip into my Doxy that was prescribed for Lyme. But for me, no matter what medication I take for COVID, if I eat mammal, I will be doubled over, or headed for the ER depending on the meat that I consumed. Eating out is nearly impossible. So I am restricted with what I can take (no capsules) but I did have on hand the Doxy tablets. All because of a tick. COVID....all because of a virus bug.
