I do not accept the framing. The question has been narrowed to the version that has a tidy answer, and the part that was dropped is the part the OP actually asked about.

Agreed on the substance. I would put less weight on the timescale, because two months of anything is not enough to distinguish a trend from a wobble.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. I will report back once I have actually tried it.

Adding the clinical framing, because it changes how the question reads. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.

Reporting back.

Update — I was wrong in the opening post, specifically about the direction. Correcting it here rather than editing it away.
