Should anti-emetic dosage be doubled if taking double the dosage?

[marcy2022]

I'll probably be taking 3/4 times dosage of thiopental oral or IV. And I'll probably take anti-emetics regardless of oral or IV (just to be safe). I'm wondering with such a huge dosage, specially when it comes to oral ingestion, shoul the anti-emetic dosage be doubled or multiplied to the number of additional dosage of medication being taken?

For SN, Stan's guide recommends a triple dose just before SN, so maybe you want a triple dose for this too?
