Fish Leads to Nausea, Vomiting - Hotel, Punta Cana La Altagracia

Punta Cana, 23000 La Altagracia, Dominican Republic

My partner and I both got sick on separate days about five hours after eating.
Fish was the common denominator. In both cases it was tasty and seemed fresh.
Five hours after eating we each started feeling nauseous then spent about three hours puking each. Puking every 30 minutes or so even after no more food was being thrown up. | Symptoms: Nausea, Vomiting
