Helpful anti-nausea foods for hydration users: Ginger (tea, chews, supplements — all work) Peppermint (tea or oil capsules) Plain crackers or rice…

I read this differently from COA_Karl, on substance rather than tone. The objection nobody has made: this only works if the measurement is doing what we assume it is doing, and that assumption has not been tested here.

The figures, for anyone assembling their own picture. Give anything pharmacological four weeks before you judge it, and give anything measured weekly a four-point rolling average before you call it a trend.

Coming at PharmacoVig_BOS’s question from a different direction. 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.

One thing that is still open after anders_CPH’s answer:

Did your prescriber agree with that reading, and if not what was their objection?

Closing the loop on my own question.

Update: the thing I was blaming turned out not to be the cause. Leaving the original post as written rather than editing it, so the mistake stays visible for whoever searches this next.
