The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either.

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.

Happy to go further on any of that.

The figures, for anyone assembling their own picture. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.

Adding the part of the answer the thread has not reached. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.

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

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

OP back with an update, since a thread like this is useless without one.

Closing this out. What actually changed my mind was the point about waiting for a trend instead of reading a single measurement, which is embarrassing in hindsight and worth saying anyway.
