Nausea arrived on day two of each dose step, lasted about four days, and disappeared entirely by the second week — until the step where it did not.

Trial-level incidence runs roughly 20 to 25% for nausea at the higher dose tiers and 12 to 17% for diarrhoea, with most events mild to moderate and concentrated in the weeks after each escalation.

The bit I cannot resolve on my own is whether holding at a lower dose for longer actually reduces total side-effect burden or just spreads it out.

If the honest answer is that nobody knows, that is a useful answer and I would rather have it.

Short answer first, then the reasoning. Holding genuinely reduces total burden rather than redistributing it, because the gastric-emptying component adapts. Receptor-level tachyphylaxis to the delayed-emptying effect develops over weeks while the central appetite effect persists, so the same dose is materially more comfortable at week six than at week two. A slower ladder therefore reaches the same dose with less cumulative nausea, not the same nausea spread thinner.

That is correct as far as it goes, and here is where it stops going. The meal advice is right and incomplete without the hydration point. People stop drinking because drinking makes them feel full, then attribute dehydration symptoms to the drug.

Ask again with the specifics and you will get a better answer than this one.

Same position here, arrived at the long way round. The line between titrate-through and stop is not severity, it is trajectory and what else is present. Nausea that peaks and improves within a week is the expected pattern. Nausea that is escalating, or that comes with severe upper-abdominal pain radiating to the back, or that prevents fluids for more than a day, is a different conversation and belongs with a clinician the same day.

Clinical perspective, offered as context rather than as advice. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.
