Collecting this in one place because it comes up every few weeks and the answer is always assembled from scratch. It is about nausea, and it is deliberately narrow — everything I am not confident about is marked as such.
What is actually established
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.
The condition it depends on
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.
The practical version
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.
What I am not sure about
What I am trying to establish is whether holding at a lower dose for longer actually reduces total side-effect burden or just spreads it out. Not looking for reassurance. Looking for the part I have got wrong.
