There is a second half to this that has not been said yet. If two explanations both fit, the useful question is which one predicts something the other does not. That is answerable; arguing about which sounds more plausible is not.

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

Follow-up: moving the tablet to the moment I wake, before anything else, was the whole fix. The dose never changed.

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

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

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. I would resist the confidence. Half of what this board was certain about two years ago has since been quietly dropped, and nobody went back to correct the threads.

True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.
