Answering the narrow version, because the broad one does not have a single answer. 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.

No disagreement with LipidDoc_ATL. One condition attached. 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.

The nausea I get is not really nausea, it is an aversion.

Same position here, arrived at the long way round. 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.

Clinical perspective, offered as context rather than as advice. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.
