Headaches on GLP-1 — looking for input

This one has a reasonably settled answer, so here it is. 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.

Agreed on adaptation, with 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 nausea I get is not really nausea, it is an aversion.

Can confirm the pattern robert_kc describes. 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.

Adding the clinical framing, because it changes how the question reads. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.
