The mechanism that matters here is not stomach emptying, it is central.

I will push back on the "any working dose is fine" framing. The maintenance evidence sits overwhelmingly at the top studied dose, and the extension data shows regain tracking dose reduction rather than tracking stopping. Holding low is reasonable; pretending it is evidentially equivalent is not.

The figures, for anyone assembling their own picture. 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.

Correct me if the detail matters more than I have assumed.

Coming at Dr.KarenChen’s question from a different direction. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

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

Did your prescriber agree with that reading, and if not what was their objection?

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

Update. I did go to 2.4mg in the end, and the honest report is that it bought me less than the step before it and cost me two bad weeks. Worth knowing rather than worth repeating.
