This is a heads-up, not a conclusion. Everything I am confident about is below; everything I am not is marked.

The nausea I get is not really nausea, it is an aversion. Food I want in the abstract becomes repellent in front of me, which no side-effect list describes.

A caveat: adaptation applies to gastric emptying and not to everything. If your problem is the aversion rather than the fullness, waiting does less, because the aversion is central and it is the mechanism working as intended.

What to check: 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.

If your experience contradicts this, say so in the thread — I would rather be corrected here than have people act on a warning that does not hold.

Agreeing with Dr.RaviCardio, and the qualification matters more than the agreement. 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.

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

I dislike how confidently this board tells people to push through. Incidence figures around 20 to 25% at the higher doses are class-typical, but the trials also had a discontinuation column, and "manageable with protocols" is not the same as manageable for everyone.

Taking the question as asked, rather than the general version of it. The practical protocol is dull and it works: smaller meals, stop eating at the first sign of fullness rather than at the end of the plate, drop the fat fraction of meals in the two days after dosing, and do not lie down straight after eating. Most of what people call unmanageable nausea is a meal-size and meal-composition problem interacting with a stomach that is emptying slowly.

Same experience, arrived at from the opposite direction.
