One concrete data point for the thread. For anyone assembling their own picture: Tmax is one to three days, terminal half-life about 165 to 170 hours, steady state at four to five weeks, and subcutaneous bioavailability near 89%. Those four numbers explain most of the questions people ask about timing.
A narrower follow-up, since the general answer is now clear:
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. Steady state is the thing most people miss. The terminal half-life is about a week, so every dose step takes four to five weeks to fully express itself. Judging a step at day ten is judging the ascent, not the plateau, and it is the single commonest reason people escalate before they needed to.

I moved the tablet to the moment I wake up rather than trying to fit it around breakfast, and the difference in the following weeks was obvious. It was a timing problem, not a dose problem.

Dr.PeteFamMed 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.
