One thing that is still open after Dr.GutHealth’s answer:

What did you change at the same time, and can you separate the two now?

Pushing back on HPLC_Greg here. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.

No disagreement, though it depends on where somebody is starting from, and this thread has been assuming a starting point nobody stated.

This answered a question I did not know how to ask.

Clinical perspective, offered as context rather than as advice. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.
