i believe chamomile tea is the best for nausea. you can buy that anywhere at any grocery store. also if there is a tea with ginger in it that is supposed to help too but it has a much more bitter taste than chamomile so if you're already feeling slightly n* you might not want such a strong flavor. chamomile is very light tasting and if you add just a little bit of honey or sugar it tastes rather well. hopefully this helps!
