Answering the narrow version, because the broad one does not have a single answer. 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.
I would rather be corrected than agreed with, if it comes to it.
