Clinical perspective, offered as context rather than as advice. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.

Can confirm. Same sequence, different timescale. I had assumed I was the exception until I read this.

Coming at anders_CPH’s question from a different direction. Worth answering the question that was asked rather than the one behind it. The narrow version usually has an answer; the broad version usually does not, and answering the broad one is how a thread stops being useful.

I would rather be corrected than agreed with, if it comes to it.

One concrete data point for the thread. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

That is the short version; the long version is somebody else's post.

Following on from anders_CPH — and this may be the naive question:

How long did you give it before you decided it was working?
