That is correct as far as it goes, and here is where it stops going. Four weeks is the pharmacokinetics, not caution. With a one-week half-life you need four to five half-lives to reach steady state, so at two weeks you are dosing on top of a concentration that has not finished rising. Escalating then stacks exposure and you get the side-effect burden of the higher dose before you have seen the benefit of the current one.

I disagree that the ladder is purely tolerability. The maintenance and regain data cluster at the top doses, so a ladder abandoned halfway leaves you outside the evidence base for the part that matters most — keeping it off.

Taking the question as asked, rather than the general version of it. Holding longer is the underrated move. A step that is uncomfortable at week two is frequently comfortable at week six with no change in dose, because the gastric-emptying component tachyphylaxes while the appetite effect persists. Escalating at week two throws that adaptation away.

Adding a me-too, because a thread of one person's experience is not much use. Posting only so the count is not one.
