Scopolamine would. It directly prevents vomiting by blocking out the acetylcholine receptors, directly preventing the gastrointestinal muscles from contracting in a way that causes vomiting. Get the datura inoxia seeds (which contains hyoscyamine) and take 10-20. Alternatively, you could grab some buscopan (scopolamine butylbromide. But I am clueless on hoe useful that is yet. Whatever you do, DON'T use the hydrobromide version (transdermal scopolamine), that likely won't do much except for motion sickness.
