I am a 43 year old male. 173 pounds, 5 9 . Many times when I eat rice (with other ingredients like in Chinese or Mexican food), I suddenly need to show it up. My gag reflex becomes so sensitive that I can t even take in water or I immediately throw up more. Usually, this lasts about 10 minutes, with me vomiting 3-4 times in that span even though I am not taking anything else in. Finally when it passes, I am fine and can eat like normal. This response is something has developed really in the last 2-3 years.
