Understood, but please consider that some proposed solutions are merely palliative in nature, whereas others are premised on basic science reaching to what may be reversible root causes of a given syndrome. I have abandoned quite a number of palliative regimens, sometimes without giving these all the time needed before they might have produced relief, but thatś because while resorting to these, I have continued to try to identify therapies that work deeply enough actually to reset whatever system or systems of ours has/have been dysregulated by COVID. Thiamine repletion/supplementation continues to strike me as one of the root cause-focused therapies that has the potential actually to restore us to health, ideally helping to improve symptoms along the way to recovery. I wish I could be optimistic about your primary care physician coming on board with thiamine therapy, but my own experience, so far, is that the most that one may reasonably expect is the approval and moral support of a primary care provider who grasps that thiamine is a direction that cannot hurt and just might help. Even long-COVID specialists, these days, seem to be locked in to a very limited set of regimens to try, most of which are merely palliative. Ǹonetheless, it is always worthwhile to learn as much as we can, and then attempt to engage our providers sufficiently so that they may themselves read and study more.
