...When you feel nauseous? What are your coping strategies? What medicine, herbs, supplements, etc. do you take, if any?

I'm wondering because there's a stomach bug going around the area where I live and my mom has caught it (we live together) so that means I'm probably next and my emetophobia seems worse this year than it has other years.

I always do deep breathing when I feel nauseous and take papaya enzyme. My aunt says that anti-heartburn medicine stops nausea. Is that true? Also, is it true that if it's been twenty four hours since the worst part of the bug, it won't get any worse than it already is?
