My A1C dropped so fast my doctor thought the lab made an error — looking for input

From the other side of the consultation, briefly. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

The figures, for anyone assembling their own picture. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

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

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

What would you measure differently if you were starting again?

Careful with the causal language. Two things moving together in a period when five things changed is not a mechanism, and stating it as one makes the thread less useful to somebody reading it later.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful.
