On 27/12/2019, I had 8 pieces original Takoyaki combo (free upgrade) at 6pm before boarding my bus. After 30 minutes, I was vomiting profusely in the bus for the next 2 to 3 hours into a full plastic bag of about 20cm. The intense vomiting hurt my stomach that I was experiencing continuous chronic hearburn and GERD symtoms. Recently, I had endoscopy which shows 30% of stomach lining is inflamed and redness. I recalled the Takoyaki I had smells really weird even though it was grilled hot.
