Adding the numbers, since they settle part of this. Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.
Following on from Dr.SportsMedIN — and this may be the naive question:
Whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong?

There is a second half to this that has not been said yet. The mechanism that matters here is not stomach emptying, it is central. GLP-1 receptor agonism in the arcuate nucleus stimulates POMC neurons and suppresses AgRP/NPY signalling, which is why the effect is appetite and food salience rather than physical fullness. Delayed gastric emptying largely tachyphylaxes over the first months; the appetite effect does not.

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

PedsEndoPhilly has the substance of this right. The condition it depends on is worth stating. The absorption variability is real, but it partly averages out over weeks — the steady-state trough is less erratic than any single day would suggest. Where it bites is in the first fortnight, when people conclude the tablet does nothing.
Happy to go further on any of that.
