One day of nausea is very common and often resolves on its own. For quick relief, over-the-counter options like bismuth subsalicylate can help soothe your stomach. If your nausea is related to motion or dizziness, antihistamines like dimenhydrinate or meclizine may be useful. Natural remedies like ginger tea and staying hydrated with small sips of water are also highly effective. If the nausea persists beyond 48 hours or is accompanied by severe pain, high fever, or an inability to keep fluids down, please consult a healthcare professional. They can prescribe stronger medications, such as ondansetron, if necessary. Rest well!
