Greatly appreciate all this additional information! I couldn´t agree more that what you and others have experienced (but not sufficiently to provide a long-term resolution of long COVID) must surely provide clues leading to solutions, based on these clues, that could indeed be lasting in effect. I routinely encounter eyes glazed over when I attempt to share with a physician what I am learning about my own favored therapies. My dentist, to her credit, is intrigued, and plans to try B1 with two members of her family who are experiencing long COVID, and she has even asked me to supply her with citations to research findings to support this approach, but that is the extent of the interest I encounter in establishment health care, so far. The silver lining here is that while we cannot self-direct a therapy based on an Rx antiviral or other restricted-access product, some of the promising therapies out there continue to be based on non-Rx nutraceuticals or OTC remedies. Yes, we take risks and leaps when we self-treat using these, but the serious damage done to my nervous and immune systems, over the past few years, via drugs prescribed by my physicians has to be factored in to the cost-benefit analyses we undertake.
