We don’t need a peer reviewed study to test it out.
CTRL+SHIFT+I and in the console
let o, a=new AudioContext();
document.addEventListener("mousedown",function(){

It would be completely bonkers for an antiemetic to commonly induce an emetic urge in any but rare exceptional cases.
Most seasickness drugs are just first-generation antihistamines sometimes combined with a caffeine analogue to counteract the sleepiness.
Dramamine/Gravol (dimenhydrinate) is just benadryl (diphenhydramine) plus the caffeine analogue theophylline.
Bonine/DramamineII (meclizine) is also a first-generation antihistamine.
Promethazine is also a first-generation antihistamine.
Non-antihistamine antiemetics like ondansetron or scopolamine transdermal patches require a prescription from a doctor and therefore aren't commonly used for motion sickness except for occupational seafarers. And it would still be absolutely stupid if the drugs given to prevent nausea commonly caused nausea.
See: antidepressants can increase suicidal ideation, cannabis (used for nausea) can cause nausea at higher doses, etc.
I think you're making the error of conflating probabilities here. It's not uncommon for drugs to have uncommon side effects, but those side effects are still uncommon. Every once in a while benadryl makes a person paradoxically excited, but most people who take benadryl get sleepy.
The nausea part. The person I'm replying to specifically said "queasy".
